What is JavaScript? What can you do with JavaScript?

If you’re not familiar with JavaScript, let’s take a few moments to go through the fundamentals first.

JavaScript is a programming language used for making websites more interactive and dynamic.

What does that mean exactly?

To understand how JavaScript works, you need to know how front-end developers build websites in general.

Here’s a quick overview of the three languages used for creating and building web pages:

  1. HTML or HyperText Markup Language:
    You can use HTML to create the basic structure and the content for a web page: menu bar, content area, sidebar, bottom footer, etc.
  2. CSS or Cascading Style Sheets:
    CSS allows you to select individual HTML elements and change their appearance. In other words, CSS makes HTML pretty.
  3. JavaScript:
    JS takes those static HTML/CSS elements and adds life to them. For example, it allows you to create elements that the user can interact with, such as drop-down menus, contact forms, modal windows, animations, interactive maps, and more.

All in all, JavaScript makes websites more engaging and interesting.

For more details, make sure to read my complete guide on front-end and backend web development.

Why learn JavaScript?

If you are new to coding and not sure whether JavaScript is the right programming language to learn, don’t worry.

Before you choose your first programming language, make sure you know what you want to create and build with code in the future.

Depending on your specialization, you need to learn a specific set of programming languages and other tools.

Hence, only learn JavaScript if it’s a language you can use for the type of projects you want to work on.

With that said, here are 5 good reasons to learn JavaScript this year:

1: JavaScript is in high demand

If you are serious about becoming a JavaScript developer, you are going to love the fact that JavaScript is one of the most sought-after skills in tech today.

According to the Devskiller IT Skills Report, 75% of companies are looking for JavaScript developers:

JavaScript is the most popular programming language that companies are looking for (Source: DevSkiller top IT skills report)

Furthermore, searching for “JavaScript developer” on the Indeed job portal returns over 20,000 jobs requiring this skill – alone in the US.

2: JavaScript developers are well-paid

So we know that there are plenty of job openings for skilled JavaScript developers. But how much do they make?

According to Indeed, the average base salary for JavaScript developers in the US is $110,687 per year.

3: JavaScript is beginner-friendly

If you are new to coding, I recommend picking a language that allows you to focus on learning how coding works and how you can build your own, useful projects asap.

Choosing an easy language means you will spend less time troubleshooting your code and trying to understand the syntax. Thus, you’ll have more time to actually learning how to code.

Luckily, JavaScript is one of the easiest programming languages for beginners.

Now, while the syntax isn’t always the easiest to grasp, you will always find answers to your JavaScript questions thanks to the massive global community of JavaScript experts. This helps you troubleshoot your code faster and makes learning how to code much easier.

4: JavaScript is versatile

JavaScript is an extremely versatile programming language. You can use it for front-end web development to create stunning website interfaces, but also for backend coding using Node.js.

Also, you can develop web apps, mobile apps, and desktop apps using React, React Native, and Electron.

If you want to become a front-end web developer, JavaScript is a must-have skill.

But you could use your JavaScript expertise in the future to work as a full-stack developer, software engineer, or game developer, for example.

Hence, even if you are new to coding and not sure what you want to do in the future, JavaScript doesn’t restrict you to just one area in tech.

5: You can learn JavaScript for free

Last but not least, learning JavaScript doesn’t have to be expensive!

If you are new to coding, I recommend starting with free resources to get a hang of how JavaScript works. You will find tons of ideas in my guide with 100+ free places to learn how to code.

If you enjoy working with the language, consider investing in a paid course that includes as many practical coding projects as possible.

Building small projects and solving coding problems is the only way to improve your skills and learn how to use JavaScript for building real-life projects.

Therefore, you want to pick a course that offers as many portfolio-ready projects as possible, such as these two courses on Udemy:

  1. JavaScript Web Projects: 20 Projects to Build for Your Portfolio
    You get to build 20 practical portfolio projects throughout the course – even if you are entirely new to programming. That kind of a portfolio is going to look great when you apply for your first entry-level job.

FAQ: JavaScript practice exercises

Where can I practice JavaScript?

Some of the best places to practice JavaScript include Edabit, w3resource,, Codecademy, and W3Schools. They all offer free JavaScript exercises and coding challengers for beginner and intermediate skill levels.

How should I practice JavaScript?

The best way to practice JavaScript is to learn the theory and syntax first. As you go, practice your skills with simple exercises, and start building more complex projects as your skills improve. The concepts build on top of each other. Thus, make sure you feel comfortable with a given topic before moving on to the next one.

How do beginners practice JavaScript?

If you are new to JavaScript, the easiest way to practice is to take breaks from following tutorials. Take notes of what you learn and try to solve small coding problems with JavaScript on your own without referring to your course or tutorial. Hence, start very small and only proceed to the next topic once you feel comfortable with what you just learned.

Can I learn JavaScript in 1 week?

You can learn how JavaScript works in 1 week, yes. You may feel comfortable enough to solve small, simple coding problems with JavaScript after a few days of learning the syntax. But it takes much longer to become job-ready and to launch a career as a JavaScript developer. Hence, one week is enough to get an understanding of whether you enjoy working with JavaScript and if you want to continue learning more about it.

Can I learn JavaScript without HTML and CSS?

In theory you can, yes, but it wouldn’t make much sense. JavaScript is so closely intertwined with HTML and CSS that you shouldn’t learn just one of them. Remember, JavaScript is used to make static websites more dynamic, interactive, and engaging. Without HTML and CSS, you won’t have anything on your website to apply JavaScript to.

Should I learn Java or JavaScript?

Whether you learn Java or JavaScript depends on what you want to build with code in the future. If you want to become a front-end web developer and create gorgeous websites, JavaScript is a must-have tool in your skillset. Java is used for back-end (server-side) development. Thus, if you are more interested back-end programming and want to build desktop apps or Android mobile apps, for example, Java can be a valuable skill on the job market.

Where can I find JavaScript project ideas for beginners?

I have written a separate article with the best JavaScript project ideas with source code – check it out!

What you need to start practising JavaScript

1. Code editor

I recommend installing a code editor on your computer, although you can use online code editors, too.

Here are a few free code editors you may want to try out:

For more options, check out my article with the best text editors for coding and web development.

2. Web browser

Since JavaScript runs directly in your web browser, you can simply write your code and instantly test it in your browser.

Make sure you use a modern web browser such as Google Chrome or Mozilla Firefox. You need good developer tools so that you can check the console for any errors in your code and debug them.

3. JavaScript tutorials and courses

If you are new to JavaScript, I recommend trying a few different resources to learn how the language works.

We all have different learning styles, and it’s important that you find out how you learn best.

If video tutorials are easier to follow than going through a physical book, be mindful of that and use materials that support your learning.

I’ve listed some of my recommended JavaScript courses here.

For even more resources, check out these top web development courses, too.

4. JavaScript syntax cheatsheet

Wrapping your head around the syntax can be tricky in the beginning. Using a cheatsheet is a quick way to save time when you need a quick refresher or want to double-check something.

I love this free JavaScript cheatsheet on Codecademy. For a compact PDF version, check out this free JS cheatsheet.

5. Portfolio for your JavaScript projects

As you work through your JavaScript practices and your skills improve, you will start building more complex JavaScript projects.

To showcase your skills and best work samples to potential employers, you want to set up a professional-looking portfolio website. It doesn’t have to be anything too fancy – a simple one-page website is more than enough to get started.

Keep your design clean and clear, and don’t be afraid to show some personality!

To help you get started, I’ve written a free step-by-step guide for creating a portfolio website from scratch.
