Overview of what we learn of this course.
In this section we configure our Visual Studio Code settings.
In this video we are going to dive Javascript codes.
In this video we are going to write our first codes.
Let’s talk about what is Javascript. In this video we are going to learn some theoretical stuff.
Let’s learn how to link our Javascript file to HTML file.
Let’s learn about values and variables in Javascript language.
In this video we are going to learn about data types. Numbers, booleans etc.
In this video we are going to take a look at the three different ways of declaring variables in JavaScript.
In this video we are going to learn some more JavaScript fundamentals. Let's learn about some basic operators.
In this video we are going to talk about the precedence of different operators.
In this video we are going to talk about strings and template literals. Strings are a very important part of programming. And so let's now learn about an easy way to build strings, using something called template literals.
In this video let's now make coding even more fun and actually take decisions with our code to make it look a lot more real.
In this video, we need to go back to value types. So types are one of the fundamental aspects in programming. And converting between types is something that we do in every programming language.
We talked about type conversion and coercion to numbers and to strings. But we didn't learn booleans yet. That's because we need to learn the concept of truthy and falsy values first. And so, that's what we're gonna do now.
We have only used comparison operators to take decisions with if else statements. But let's suppose we want to check if two values are actually equal, instead of one being greater or less than the other. And for that we have different equality operators.
When we learn about if-else statements, comparison and equality operators and boolean values. We also need to learn about logic. And in particular about boolean logic. So let's do that in this video.
Logical operators are really important in Javascript language to make decisions. Now let’s talk about that.
In this video let's learn about the switch statement, which is an alternative way of writing a complicated if/else statement, when all we want to do is to compare one value to multiple different options.
Now that we're getting more comfortable with JavaScript, it's time to learn about a more theoretical concept. And that's the difference between statements and expressions.
We already saw two ways of writing conditionals. The regular if/else statement and the switch statement. But there is another one. And that is the ternary operator.
Now before continuing to learn JavaScript, in this new section, we should first activate a special mode in JavaScript, called Strict Mode.
The fundamental building block of real world JavaScript applications are functions. They are one of the most essential concepts in the language. And so let's study functions over the next couple of videos.
In JavaScript, there are different ways of writing functions. And each type of function works in a slightly different way. Now let’s learn about declarations and expressions.
So we learned about function declarations and expressions in the last video. But there is actually a third type of function that was added to JavaScript in ES6. And that's the arrow function.
Let's now take functions even one step further and call one function from inside another function. And this is something that we do all the time in JavaScript.
To finish this part about functions, let's review everything important that we learned so far. In order to make sure that you really understand functions before we move on to other topics.
Data structures are the most important topic in Javascript. Let's now talk about our first data structure. And that's gonna be Arrays.
JavaScript has some built in functions that we can basically apply directly on arrays. And these are called methods. And we can think of methods as array operations basically. So let's now learn some useful array methods.
After arrays, it's now time to learn about another data structure in JavaScript, which is objects.
In this video, we are going to learn how to retrieve data from objects. And also how to change data in objects, using both the dot and the bracket notation.
In this video let's keep exploring objects. And this lecture will bring us to object methods.
When we talked about the if else statement, I mentioned that it's a control structure. And also, there are more control structures. One of the other control structures are loops. And loops are our final big topic in this section.
Let's now explore some more features of the for loop and also create a somewhat more useful example.
In this video, we're gonna do two interesting things. First, we will loop over an array backwards, and then second we will also create a loop inside another loop.
So we learned all about the for loop and even created a loop inside a loop. But there is another type of loop in JavaScript and that's the while loop. So let's explore that one now.
Welcome to the first project that we're gonna build in this course. And let's get started right away.
So in this section, we're going to make JavaScript interact with a webpage for the very first time. And the technical term for that is doing DOM Manipulation. Let's learn what the DOM actually is and how it works.
Now that we have a better understanding of what DOM and DOM manipulation. Let's now actually select and manipulate some more elements.
I Let's now make our application actually do something when we click on the button. So this is going to be the first time that our code reacts to something that happens in the DOM. For that, we will use event listener.
Let's now continue building our game and actually implement the game logic itself. First, we will implement compare logic.
In the last video, we implemented the compare logic. We compare input value to hidden number. And due to the comparison, we printed a status message. Now, let's move on to the next step. Which is to work with a score here.
The DOM actually also includes CSS styles. And so with DOM manipulation, we can also change styles. So let's try that out now
Let's now implement the functionality of reset the application.
So let's now implement the last missing functionality in our game, which is the highscores.
To finish this project, let's now learn about the refactoring in order to get rid of some of our duplicate code.
Now we're going to do a nice project again. The name of our project is rock paper scissors.
In the previous video, we talked about the details about the application we will do. Now let's get to work. Let's define the elements we will use.
We defined the DOM elements that we will use in the previous video as variables. Now let's start creating the logic of our game. First of all, let's make computer and player choose.
In the last video, we created the computer's move randomly and we made our own move by clicking the rock paper and scissors buttons. Let's continue now.
In the previous video, we created our play game and display messages functions. When we clicked on the rock paper and scissors buttons, we displayed the messages on the screen according to the selections. Now we can start coding the actual logic of our game. Let’s compare choices and get result.
In our previous video, we determined the winner of the game and showed it on the page. Now we will update the score and build the game over functionality.
In the previous video, we completed all the functions of our game except the reset function. In this video, let's quickly create the reset function and finalize the project.
As an introduction to this theory section, I want to start with a very cool and very high-level overview about the JavaScript language.
We talked about the JavaScript engine in the last video. But what is that engine actually? And what is a JavaScript runtime? Also, how is JavaScript code translated to a machine code? So that's just some of the topics that we talked about in the last video. And so now let's find out how they work in this video.
In this video, let's answer the question. How is JavaScript code executed? We already know that it happens in a call stack in the engine, but let's dig a bit deeper now.
In this lecture, let's answer the question. How is JavaScript code executed? We already know that it happens in a call stack in the engine, but let's dig a bit deeper now.
In this video we need to talk about is a very misunderstood concept in JavaScript and that is hoisting.
The this keyword, is an extremely important concept to understand in JavaScript. And many beginners find it especially difficult. But don't worry, It's actually not that hard if you know exactly how the this keyword works.
Let's now see the rules of how the this keyword is defined in action.
Let's start this video by learning about array destructuring.
We talked about these destructuring arrays, but we can also destructure objects. So let's do that now.
Let's now talk about the amazing spread operator. We can use the spread operator to basically expand an array into all its elements. Basically unpacking all the array elements at one.
Let's now talk about the rest operator. And the rest operator looks exactly like the spread operator. So it has the same syntax with the three dots, but it actually does the opposite of the spread operator.
Let's talk about the AND operator and the OR operator. And how we can use them for something called short circuiting.
In this video we will learn how to work with strings. And so we're gonna be taking a look at a couple of useful string methods.
Let's continue with some simple string methods. And first ones are for changing the case of string.
Let's start by learning about one of the most powerful string methods, which is split.
Let's begin this video by introducing a couple of simple and easy-to-understand array methods. These methods: slice, splice, reverse and concat.
In JavaScript, the "forEach" method is a powerful tool that allows developers to iterate over elements in an array and perform operations on each element individually. This video aims to provide an in-depth understanding of the "forEach" method and its practical applications.
One such essential method is the map function. The map function allows developers to transform and manipulate array elements effortlessly, providing a concise and elegant solution. In this video, we will explore the map function in JavaScript and various practical examples to demonstrate its utility.
In this video, we are going to learn about filter method. Filter function, which allows developers to easily extract elements from an array based on specific criteria. With its concise syntax and powerful capabilities, the filter function simplifies array manipulation tasks, making code more readable and efficient. In this video, we will explore the filter function in JavaScript in depth, purpose, and various examples to demonstrate its practical usage.
Reduce method which allows developers to transform and aggregate arrays into a single value. In this video, we will explore the `reduce` method and delve into its various applications. By the end, you will have a solid understanding of how to leverage the `reduce` method to simplify your code and enhance your JavaScript programming skills.
One such method is the "find" method, which allows developers to search through an array and locate the first element that satisfies a given condition. The "find" method is particularly handy when dealing with complex data structures and is widely used in modern JavaScript applications. In this video, we will explore the "find" method in detail, understand its syntax and functionality, and provide basic code examples to demonstrate its practical usage.
JavaScript provides several built-in methods to perform various operations on arrays, including the popular `flat` and `flatMap` methods. These methods are particularly useful when dealing with nested arrays or when you need to transform and flatten arrays in a concise and efficient manner. In this video, we will explore these methods in detail, along with basic code examples to illustrate their usage.
In the world of programming, sorting arrays is a fundamental task that developers encounter frequently. Whether you're organizing data, implementing search algorithms, or optimizing performance, having a solid understanding of array sorting techniques is crucial.
Let's start this section by understanding what asynchronous JavaScript actually is, and also learn about the most popular use cases of asynchronous JavaScript, which is basically to make so-called Ajax calls to APIs.
Now that we know about AJAX and API's, let's actually make our first API call.
In this video, let's create a sequence of AJAX calls, so that the second one runs only after the first one has finished.
In this video, let's learn about a modern JavaScript feature called promises, so that we can escape callback hell.
In this video, we will learn how to consume a promise. And in this case, we will consume the promise that was returned by the fetch function.
Let's now learn how to chain promises in order to also show the border countries of the initial country that we give to the function.
Until now, we have always assumed that everything went well with our AJAX calls, so we never handled any errors. However, an important part of web development is to actually handle the errors. Because it's very common that errors happen in web applications. And in this video, let's talk about how to handle errors in promises.
In this video, we're gonna fix the request 404 error that we saw happening in the last video.
In this video, we will talk about during the course of the topics we'll cover in general. What you'll be familiar with the topics that we will learn.
In this section, we will learn what Vue.js is. We will briefly talk about the main features of Vue.js.
In this section, we will talk about the advantages of Vue.js. We will tell you the benefits of these.
In this section, we will talk about two-way binding, Virtual DOM and Component structure, which are the main features of Vue.js.
In this section, we will see the Node.js installation.
In this section, we will talk about the Vs Code application. We will start from scratch with the CDN installation.
In this lesson, we will connect a project from scratch to our application with CDN links. We will embed an HTML tag in our application.

FAQs about Vue, Vuex, Javascript
What is Vue JS?
Vue (pronounced like view) is a frontend development framework for JavaScript (JS) that you can use to build web-based user interfaces. You can also use it to create one-page applications and handle animations, interactive elements, and graphics. Generating projects is also possible with the user-built presets, which is commonly applicable for coders working in enterprise environments. Because it is based on JavaScript, you can easily integrate Vue into an existing JS project. Vue uses the traditional Model-View-Controller (MVC) architecture, which means that the core library of Vue.js focuses on the view layer by default. It enforces a one-way data flow between components. This also makes it easy for you to integrate with other libraries or existing projects. Vue also uses virtual DOM (Document Object Model), which makes it faster than regular DOM. Instead of re-rendering the whole page, Vue only updates the objects that you change.
What is the difference between Vue and React?
Although Vue has an MVC architecture, you cannot use it with a different architectural approach, which differs from the Component Based Architecture (CBA) used in React. They also differ in how they optimize data. When a component’s state changes in React, it triggers the re-render of the entire component sub-tree, starting at that component as the root. Vue automatically tracks a component’s dependencies during its render, so the system knows which components actually need to re-render when the state changes. In React, everything is in JavaScript. Vue, on the other hand, embraces web technologies like HTML, CSS, and JavaScript and allows you to build off of them. Another difference between these frameworks is how you can scale up your projects. React only offers a single template that assumes you’re building a single-page application, while Vue offers several default options for multiple purposes and build systems.
Is Vue JS easy to learn?
Vue JS can be easy to learn. Unlike other frontend technologies, Vue doesn’t require in-depth knowledge of libraries. If you want to start learning Vue, all you need to have is basic knowledge of HTML, CSS, and JavaScript. Compared to other coding technologies, developers typically classify Vue.js as having an easy learning curve. This is due largely in part to Vue’s reputation for having an elegant programming style and patterns. Because Vue is a progressive framework, it makes it easy for you to use it to integrate into an existing project. Because of its familiar templating syntax and use of components, you may find that integrating or migrating existing projects to Vue is fairly straightforward. Vue is known for offering a vast ecosystem of tools and companion libraries, making it a simple framework that you can use to respond to the complex needs of enterprise-grade applications.
What is Vuex used for?
Vuex is a state management pattern + library for Vue. js applications. It serves as a centralized store for all the components in an application, with rules ensuring that the state can only be mutated in a predictable fashion.
What is difference between Vue and Vuex?
Vue is a progressive Javascript framework and Vuex is the state management tool. We can use redux or flux inside Vue, But Vuex is native to the Vue.
Why do I need Vuex?
Vuex is a popular way to handle a complex app's authentication in Vue. With Vuex, you're able to handle the token's availability and access controls and route blocks throughout your app. Mutations, getters, and setters assist with this task.
How does Vuex store work?
It works by having a central store for shared state, and providing methods to allow any component in your application to access that state. In essence, Vuex ensures your views remain consistent with your application data, regardless of which function triggers a change to your application data.
When Should I Use It?
Vuex helps us deal with shared state management with the cost of more concepts and boilerplate. It's a trade-off between short term and long term productivity.
If you've never built a large-scale SPA and jump right into Vuex, it may feel verbose and daunting. That's perfectly normal- if your app is simple, you will most likely be fine without Vuex. A simple store pattern (opens new window)may be all you need. But if you are building a medium-to-large-scale SPA, chances are you have run into situations that make you think about how to better handle state outside of your Vue components, and Vuex will be the natural next step for you.
What is JavaScript?
JavaScript is a curly-braced, dynamically typed, prototype-based, object-oriented programming language. It started as the programming language for the web and is one of the three layers of standard web technologies — the other two being HTML and CSS. JavaScript allows you to create and control content dynamically on a web page without requiring a page reload. Web browsers are able to interpret it, and when triggered by events, modify the HTML and CSS of a web page with dynamic updates. JavaScript also uses asynchronous calls to fetch data from web services in the background. Although it was initially only used in web browsers, JavaScript engines have since been put to use as servers with Node.js, included in desktop application frameworks like Electron, and embedded in phone frameworks like Apache Cordova.
Why is JavaScript important?
JavaScript is the programming language that allows users to interact with the websites that they're visiting, making it a very important language for web developers to know. In the past, most developers focused on the backend; JavaScript was only relevant when they needed to use visual effects. As web development evolved and the focus shifted towards user experience, programmers started to rely on JavaScript for their frontend code heavily. Today, most sites use JavaScript to fetch and submit data, use logic, and generate HTML in browsers. JavaScript can also communicate asynchronously with data servers in the background without interrupting the user interaction in the foreground. These features make JavaScript not only an important language but a necessary language for modern web development.
What are the main uses of JavaScript?
JavaScript is a text-based programming language used for client- and server-side development. Web developers have used JavaScript since its inception to add simple interactivity to web pages like modals, animated elements, or image slideshows. While that is still one of its primary uses, Javascript has evolved to building complete web applications. SPAs, or single page applications, depend on JavaScript-based frameworks like React, Angular, and Vue to bring a desktop-like application experience to the browser. However, it's important to note that web browsers aren't places that make good use of the programming language. Javascript is also popular for building web services and back-end infrastructure with Node.js. React Native, Xamarin, Ionic, and NativeScript frameworks use JavaScript for developing phone apps as well.
React vs. Angular vs. Vue: what is the best JavaScript framework?
Choosing the best JavaScript framework for your web project depends on what you are looking for. React is a popular framework, which means you will find a lot of community support if you need help. It is also considered relatively easy to learn but is being developed at a rapid pace. Angular is a framework that makes data binding easy so that you can template an application faster. It also uses the RxJS library to simplify asynchronous programming and Typescript (which compiles to JavaScript) for a cleaner, less error-prone development process. Some cons of Angular are that it can have a steep learning curve and can be complex. Vue is a lightweight framework, so it is easy to learn, very performant, and flexible. Some cons of Vue are limited plugins, and its flexibility can lead to irregular code.
What is JSON and what is it used for?
Because of the evolution of the JavaScript language, JavaScript has a variety of techniques for creating objects. But, ultimately in the background, JavaScript is using a syntax called JSON. JSON stands for JavaScript Object Notation and is a standard text-based format used to represent objects in JavaScript. The same basic types of data represented in Javascript can also be represented in JSON, including strings, numbers, arrays, booleans, and JavaScript objects. Although JSON is based on the JavaScript object, it is not just used in JavaScript. It is also used as a format to transfer data from a web browser to a server and vice versa because of the format's simplicity and small size. The JSON format is used in REST APIs for this purpose and has replaced XML as the standard format for many APIs. Because of this, just about any language you use will have a method of converting data into JSON to interact with REST APIs.
How can I teach myself Javascript?
One of the best ways to learn to write code is through an online course that teaches you how to write JavaScript with an instructor that will explain the code, what versions you should use, and why. Learning to develop a real-world application, with an instructor explaining in a step-by-step fashion, will teach you modern code techniques.
What is the best IDE for Javascript?
With all of the different JavaScript IDEs available, the best option depends on how you intend to use it, along with your personal preferences. Webstorm is a popular JavaScript IDE from JetBrains. It provides fast static code analysis, integrated testing, local history, code refactoring, and debugging. While the IDE requires a paid subscription, many developers swear by it because of its compatibility with JavaScript, HTML, and CSS. Those searching for a free option might prefer VS Code. This general-purpose, open-source IDE comes with IntelliSense, Git integration, and debugging features built-in. Many third-party extensions are available to add new language and programming features, making it one of the more flexible choices. Atom is another general-purpose IDE that is popular with JavaScript developers. It is also free, open-source, and has third-party extensions to add functionality.
