react:In this lesson, we will explain the advantages of developing applications with React.

What is React?

React is a front-end library in Javascript that was developed by Facebook. The simplest definition of React is that it is a user interface library used for building UI components for the web. But if that was all React did, it would be little more than a template library. Developers define components in React by using an HTML-like syntax called JSX. These encapsulated components manage their own state, making it simple to pass rich data to a component and keep the state of the application and its components out of the Document Object Model (DOM). These features give React components the ability to react dynamically and efficiently to changes in their state. A set of simple components in React can be composed into either simple single-page applications or large, complex web applications.

What is React used for?

React is an open-source JavaScript frontend library. Some developers consider it a frontend framework because it does more than standard libraries usually do. The most common use of React is to build dynamic user interfaces for single-page web applications. But the structure of React makes it useful for more than just creating websites. JSX, which is one feature of React, is a syntax extension for Javascript that provides a template for the HTML and manages the state of the element. But JSX can be used as an interface for things other than HTML. React Native uses React to build mobile applications. Here, JSX becomes an interface for mobile UIs instead of HTML. There are even a few libraries that use React and JSX to interact with and manage hardware like React Hardware.

Web development with react, redux, nodejs, express, mongodb: In this lesson we will look at the difference between React and pure JavaScript.

Why is React so popular?

There are many reasons why React is popular. One reason is that Facebook developed it. The social proof is that if it is good enough for Facebook, one of the most popular social networks on the web, it should be good enough for other applications. React also solved many of the past issues that developers had with developing single-page applications (SPAs). React came out when SPAs were becoming popular, and all the existing frameworks to build them made development complicated and prone to bugs. One feature that makes it better than past libraries is that React is relatively easy to use. Its components are reusable, plus React's use of the virtual DOM makes it very performant. React should remain popular in the future as each new release brings new features and performance improvements.

web application, react js, redux, express js and react: .In this lesson, we will install the tools we will use while developing applications with React.

What is the difference between React Native and ReactJS, and which one should I learn?

React, or React.JS, is a front-end Javascript library for building UI components for the web. If you are interested in web development, React is the perfect library to learn to create interactive, dynamic single-page apps, or even full-scale web applications. React Native is a framework for building native mobile applications for both the Android phone and Apple's iPhone. React Native is still React, which means the syntax and workflow for building applications are basically the same, but the generated components are different. In React, web components are generated. In React Native, the generated components interact with a phone's native APIs. If your focus is web development, then you should learn React. If you want to build mobile applications, it is best to learn React first and become familiar with the technology before you try React Native.

In this lesson, we will examine the React official documentation site.

Is React hard to learn?

Every technology or programming language has a learning curve, and React is no different. But it is easy to learn if you are dedicated and determined to create frontend web applications. To make learning React simpler, you should stick to the basics of React before you add any extra libraries, as that will only complicate your learning experience in the beginning. Since React is a Javascript framework, a solid grounding in Javascript will give you a head start. With this knowledge, the unique concept of JSX, React's templating language, and the way React uses state will be much easier to grasp.

In this lesson we will try to use React in an application without an easy installation tool.

Next.js is a React framework that gives you building blocks to create web applications.

In this lesson we will learn create-react-app, an easy setup command that I use when developing an application with React.

What is React Used For?

• Social Media Platforms (Facebook, Instagram, Pinterest, Twitter)

• Economy platforms (Airbnb, Lyft, Uber)

• Media Platform (Yahoo!)

• Online Video Streaming Platforms (Netflix)

• SaaS Tools (SendGrid, Asana, InVisionApp, Zapier)

In this lesson, we will learn how to develop a single page application with React. For this, we will explain the logic in index.js.

Difference Between React and Next JS

Well, if you use Next JS and React for your development project, you will find many perks and drawbacks of using these for React/JavaScript projects. However, these are the important front-end development tools that offer a seamless and engaging web development experience. However, they have different learning curves, although they both are easy to learn.

In this lesson, we will explain the errors you may encounter as you develop an application with React for the first time. We will teach you how to interpret these errors.

Next JS vs React: Performance

The major difference between Next JS and React JS is performance.

If we talk about Next.js applications, they are extremely fast because of the static destinations and server-side rendering. Of course, they are viable due to many performance enhancement features, such as Image Optimization.

As a result, if you pick Next.js for your project, you will get automatic server rendering and code-splitting, which will enhance your development performance. Furthermore, SSR also plays an important role in better app performance.

In this lesson we will create a component. Then we will learn how to use this component in our application.

Next vs React: Documentation

The documentation section gets the most attention while finding out the difference between React and Next JS. Good documentation may help you find out how to use tools, which libraries to use, and many other things for any project development.

In this lesson we will examine the structure of JSX. We will talk about the properties of the JSX field.

Next JS vs React: Server-side Rendering

While talking about another feature – Server-side Rendering, Next.js supports SSR. It actually collects data and renders each request every time you need to deliver a different view for various users.

React does not allow server-side rendering by default, although it can be enabled. It just takes some extra effort to integrate SSR with your preferred server and setup. Besides, the developers may not support this for the next versions.

In this lesson we will create more components. Then we will learn how to nest these components.

Next JS vs React: Configuration

Another difference between Rect and Next JS you should consider is configuration. React doesn’t offer great support for configuration. Unless you disconnect from the standard Create React App, you won’t be able to change the setups. Hence, you’ll need to use what’s already set up or configured in CRA’s read-scripts.

On the other hand, everything is configurable with Next.js. The NextJS templates allow you to configure files such as babelrc, jest.config , and eslintrc .

In this tutorial we will learn how to perform JavaScript related operations in React components.

Next JS vs React: Maintenance

Both Next.js and React.js have fairly opinionated CRAs in this circumstance. They are well-maintained and release updates on a frequent basis. All you have to do now is keep up with the new updates.

In this lesson, we will learn the different perspectives that React and pure JavaScript bring to the concept of separation of concerns.

Is Next JS Better Than React?

Next.js offers easy-to-code functionality compared to React. When it comes to writing code, Next.js requires less code, whereas React framework requires a long line of coding.

React can be the right choice if you wish to build a large complex web application with complex routing and heavily data-driven components. Next.js can be a good choice for you if you wish to build a static website or JAMstack application.

In this tutorial we will learn how to do styling with React.

Next.js offers easy-to-code functionality compared to React. When it comes to writing code, Next.js requires less code, whereas React framework requires a long line of coding.

React can be the right choice if you wish to build a large complex web application with complex routing and heavily data-driven components. Next.js can be a good choice for you if you wish to build a static website or JAMstack application.

In this lesson we will learn the concept of props. We will learn how to manage data exchange between props and components.

Why learn Next.js?

Next.js offers several advantages over traditional React development:

1. Built-in Routing and SSR: Unlike React, which lacks native routing, Next.js provides seamless routing functionality out of the box. Additionally, it supports server-side rendering, improving performance and SEO.

2. Faster Development: Next.js accelerates development by offering built-in features and conventions. Developers can focus on building features rather than configuring complex setups.

3. SEO Optimization: Next.js enhances SEO by addressing slow rendering and loading times associated with client-side rendering. Its SSR capabilities ensure that search engines can efficiently crawl and index your content.

In this lesson we will explain the concept of props and data flow through diagrams.

What is Next.js used for?

Next.js is a React framework for building full-stack web applications. You use React Components to build user interfaces, and Next.js for additional features and optimizations. Under the hood, Next.js also abstracts and automatically configures tooling needed for React, like bundling, compiling, and more.

In this lesson, we will learn how to render lists with React.

Is Next.js better than React?

Next.js is definitely newer and faster in many cases when compared with React. JAMstack a modern web development architecture that uses JavaScript, APIs, and pre-rendered Markup, Next.js is the best choice for them.

In this lesson we will learn how to render lists conditional on a condition.

In this tutorial we will continue to see the conditional rendering that we learned in the previous tutorial.

In this lesson we will do conditional rendering in JSX domain with ternay method.

In this lesson we will see how to use data captured as props in a component. In this tutorial we will learn how to open incoming data.

In this lesson we will learn how to use container elements in JSX.

In this lesson, we will learn how to give a className dynamically in the JSX area.

In this lesson, we will cover the topics we will see in the chapter.

In this lesson we will start an application that we will use to learn the concepts of state and event. We will complete the static part of the application.

In this lesson, we will give events to buttons. Thus, we will start using events in React.

In this lesson we will discuss the concept of state through reflection.

In this lesson we will create our first state using useState.

In this lesson, we will talk about the pitfalls of manually changing the state value.

In this lesson, we will create buttons that allow the application page to have a drop-down structure.

In this lesson, we will talk about React Developer Tools, an efficient tool that we can use while developing applications with React.

In this lesson, we will learn how to update the state value in a more guaranteed way.

In this lesson we will introduce the application we will develop.

In this lesson, we will create the components and page layout that we will use in our application.

In this lesson we will render a list using fake data. Thus, we will also take care of the visual part of our application.

In this lesson we will start using the form component on the main page to enter data.

In this lesson, we will turn the elements we use in the form such as input and select into controlled elements.

In this lesson we will talk about the intricacies of directing state. We will explain the importance of file structure when creating a state.

In this lesson, we will explain the lifting state up method that we will often use when using state.

In this lesson, we will delete a product in the list. We will use event to do this.

In this lesson, we will learn how to cross off a product in a list when the shopping is completed.

In this lesson, we will use the number of products in our list and the number of completed products to create the footer widget.

In this lesson, we will sort according to the order entered from the input and according to the completed product status.

In this lesson we introduce our application.

In this lesson, we will start a project from scratch. Then we will delete the parts we will not use. We will finish the lesson by creating the file structure.

In this lesson we will create the static structure of our components. Thus, the skeleton of our application will be formed.

In this lesson, we will pull the data that we have created. Thus, the main body of our application will be formed.

In this lesson, we will use the data we captured in the previous lesson. We will create card structures with this data.

In this lesson we will see the life cycle of a class-based component structure. We will learn that there are separate hooks used in each section.

In this lesson, we will start learning the Class-Based component structure through a counter example.

In this lesson, we will learn how to use events in the Class-Based component structure.

In this lesson, we will talk about the differences between Class-Based component structure and Functional component structure.

In this lesson, we will start explaining the useEffect hook.

In this lesson, we will start using the features of the useEffect hook through the counter example.

In this lesson, we will learn how the useEffect hook will act when a state is included in the dependency array.

In this lesson, we will learn how to use the return field in useEffect. This field becomes active after the component is removed from the dom tree.

In this lesson, we will learn how to pull data from an API source with useEffect and useState hooks. In React applications, useEffect and useState are hooks that are often used together. This binary allows us to make React components more dynamic.

In this lesson, we will perform a data extraction using useEffect and useState again. We will start using the incoming data.

In this lesson, we will create the component structure using the incoming data. We will do styling.

In this lesson, we will learn how to use axios, a 3rd party data extraction library. We will also use the async-await structure and try-catch block in this data extraction process.

In this lesson, we will explain what we will do in the section.

In this lesson, we will learn to manipulate HTML tags by referencing them. We'll do this in pure JavaScript.

In this lesson, we will learn why we should use the useRef hook when referencing HTML tags. We will also explain other operations that can be done with the useRef hook.

In this lesson, we will reference HTML elements with useRef this time.

In this lesson, we will explain what a custom hook means. We will explain why we need to create a custom hook.

In this lesson we will make a counter example. In this example, we will create functions in the custom hook that allow the values to decrease and increase as the button is clicked.
