Hi and welcome to " Let's JavaScript! ".  

My name is Kauress and you may know me from the “Introduction to git” class on SitePoint

JavaScript is known as a front end language for web applications. According to the Developer Survey of 2016 by Stack Overflow, JavaScript was surveyed to be the most commonly used programming language on the web.

Learning a new language can be complicated and time consuming. Let Kauress guide you through beginners projects in JavaScript and the DOM! You will code 5 projects in JavaScript from scratch. Building upon basic concepts and applying them in your projects. The projects you code will allow you to manipulate user input and build dynamic web components of an otherwise static web-page. And by the end of this project series you would have coded 5 productivity web-apps in JavaScript

Code your way into learning JavaScript and Let’s JavaScript! 

Goal of the project series: 

To teach the basic constructs of JavaScript by coding projects.

The projects:

This is a complete hands on series and the projects we will be coding are:

1.  A single operation calculator:   The calculator allow you to add, subtract multiply and divide 2 numbers with or without a decimal point. Our calculator will also have A backspace and clear feature. Our calculator will automatically start new calculations after the equal to operator is clicked. Eval has not used!

2. A to-do List :  A to-do list based on arrays and array methods which will allow you to add, strike through or delete individual items and additionally you can also add an item using the enter key on your keyboard and then clear the list

3.Pomodoro:  A pomodoro is a productivity method to track work and break durations, the pomodoro will have functions such as start, pause and reset. And it will automatically start the break duration after the work period is over

4. WYSIWYG editor: A what you is see is what you get editor which will have all the basic features of a standard text editor such as bold, center align , color text and so on. This project include new topics like local storage, which will allow your draft to be saved even after you refresh the page

5. Calender widget:  A calendar widget that shows not only the current , previous and next day but also the current time and local weather. And in this project you will be use the date and time objects and an API

What are the per-requisites? 


2. CSS

3. Basic know how of JavaScript theory

This series assumes little to NO knowledge of coding in JavaScript.

This project series is best suited to those that have had little exposure to JavaScript in the way of reading material and basic definitions but have no real experience coding in JavaScript.

What if I am an absolute beginner? :

Now if you have absolutely no exposure to JavaScript in any way shape or form, you may still do the projects.  You can extend your learning experience by referencing basic definitions and, other reading material along with the content provided in each project

When you finish this course, you will be able to:


in JavaScript from scratch


your work to potential employers


on to do intermediate level projects in JavaScript

What tools do I need to do the projects? :

  1. A code editor (This part is covered in Section 2, lesson # 2)
Who this course is for:
  • Beginners
