Getting started with web development can seem intimidating. That’s because designing a website requires a mastery of multiple coding languages. If you’re an aspiring developer or designer, you might know that JavaScript is essential knowledge, but you may be unsure about where to begin acquiring this skill.

Luckily, there are plenty of simple ways to learn JavaScript. You can find tons of free resources online to help you become an expert in this programming language. From lessons to projects and educational games, you’ll likely discover something that suits your particular learning style.

In this article, we’ll introduce you to JavaScript and what it is typically used for. Then, we’ll recommend some helpful websites that you can use to start learning JavaScript for free. Let’s get to it!

A Brief Introduction to JavaScript

JavaScript, commonly abbreviated as ‘JS’, is a programming language primarily used to create complex features on websites. HTML, CSS, and JavaScript make up the framework of web design.

You can think of HTML as the most basic component, CSS as defining fundamental visual elements, and JavaScript as the code that handles the most advanced features. For instance, JavaScript is responsible for most interactive content on the web.

For example, browser games function thanks to JavaScript events. When you use an interactive map, you’re looking at JS as well. Features like clicking and dragging routes, loading local data, and even animations depend on this core language.

Essentially, HTML and CSS are used to define the basic look and makeup of elements on the web. JavaScript allows those elements to do more than just statically display information on the screen.

Furthermore, JavaScript is used to animate objects both large and small on the web. This can be as simple as a notification icon for an app or as complicated as a weather radar map. Essentially, JavaScript controls how CSS elements function in order to create powerful animations with only a few lines of code.

You might want to think of JavaScript as the conductor of an orchestra. HTML is the instruments, CSS is the performers, and JavaScript is running the show.

Why You Might Want to Consider Learning JavaScript

As we mentioned before, JavaScript is one of the three primary coding languages on the internet. Simply put, pretty much all web designers will likely need to learn JavaScript in order to create interactive content for the front end of websites. This type of web design can be as simple as a carousel for an image gallery or as complicated as an application with server-side API.

In a nutshell, if you want to reap all the benefits of creating websites from scratch, and also incorporate modern features into your designs, you’ll need to know JavaScript. Virtually all websites use JavaScript to some extent.

Whether it’s as a hobby or for professional reasons, learning HTML, CSS, and finally JavaScript can be a lot of work. However, as our world becomes increasingly digital, the demand for skilled coders continues to grow. As such, your efforts will likely pay off in the long run.

The downside of passive methods of learning such as reading a textbook or watching a how-to video is that you don’t get hands-on practice. You can try to apply what you read or watched on your own, but this can be hard without guidance. is an interactive environment that allows you to read short tutorials and then experiment with real coding, all within your browser. The fact that you are able to learn and immediately apply that knowledge in a real-world application can make it very effective:
