What is JavaScript?

In short: JavaScript is an object-oriented programming language used in web development. It’s main purpose is to breathe life into static websites.

The most important thing to know about JavaScript is that it’s part of every Web Developer’s toolbox.

JavaScript works together with two other languages to create the visible parts of any website: HTML and CSS.

In two previous posts on my blog, I discussed how to get started with HTML as well as the fundamentals of CSS in more detail.

  1. HTML stands for HyperText Markup Language and it is the starting point for any website. Web developers use it to create the structured content for web pages, such as text, images, and other media, for instance. However, HTML doesn’t really do much to make a website look nice and easy to use. That’s what CSS is for!
  2. CSS, short for Cascading Style Sheets, is the language that creates the styling for the awesome content you first create with HTML. It lets you unleash your creativity with colors, typography, layouts, and much more. In other words, CSS creates the desired look and feel for a web page.

But how does JavaScript work together with HTML and CSS?

Websites created with just HTML and CSS are mostly very static and they don’t allow for much interactivity with the user. But with a little bit of JavaScript, you can easily breathe life into the different elements on your website.

That being said, JavaScript is an essential skill to learn if you want to become a Web Developer in the future. You can use it to create dynamic and interactive web page elements, making your website more user-friendly.

What is JavaScript used for?

JavaScript is pretty much everywhere you look on the Web. It can store user inputs in variables, run functions with them, do math for you, or simply manipulate the contents of the website when needed.

So what would be some practical applications of JavaScript then?

Once you learn some JavaScript basics, you start seeing JavaScript applications everywhere on the Web. Ranging from interactive maps and timed updates for web page contents to beautiful animations – that’s all JavaScript working in the background.

Here are a few practical examples of what JavaScript can do for you:

  1. Make websites behave more individually, respond to user interaction
  2. Build web apps and games
  3. Compute and visualize data in spreadsheets
  4. Access and process information on the Web, e.g. find out what’s trending on Twitter

And these are just the tip of the iceberg, really.

With solid JavaScript skills, you could also create browser-based games or mobile applications. And although web browser have certain limitations to the complexity of web-based games, JavaScript is still a powerful tool for game development.

Is JavaScript easy to learn?

This is one question that always comes up when it’s time to learn a new programming language. Or it is for me, at least.

To be clear, it’s unlikely to find a programming language on this planet that’s explicitly easy to learn. It’s like learning anything else that’s new to you. You’ll need to work hard to see results.

But the truth is:

Some programming languages are easier to learn than others. This has a lot to do with how you use them and how they read.

For example, Python reads a lot like English, which makes it a beginner-friendly programming language.

Out of the three front-end development languages (HTML, CSS and JavaScript), it is of course the most difficult one to learn. But that’s just because HTML and CSS are markup languages rather than programming languages.

I’m not saying HTML or CSS are easy to learn, but they have a different sort of complexity to them.

How to learn JavaScript fast

Although you’ll need heaps of time to learn JavaScript and fully understand how the language works, you can start building meaningful projects early on.

And that’s what it all boils down to: applying what you learn to build programs on your own.

So, when you start learning JavaScript (or any other programming language), make sure you don’t just watch video lectures all day long.

While you’re going through your lectures, take notes. Then, after each lecture, try to use what you just learned to build a small program on your own.

If it feels difficult, look for help in your notes first. They should be good enough to remind you what to do. And if not, take better notes during your next lecture!

But why should you take notes? Can’t you just go back and watch your video lecture again?

You can, yes. But that kind of “monkey see, monkey do” approach won’t help you learn how to code by yourself. May sound harsh, but that’s the reality.

When I started learning coding, I was watching video lectures and repeating whatever exercises they showed. I felt like I was doing progress, but I soon noticed that when I didn’t have those lectures at hand, I couldn’t build anything by myself.

Therefore, don’t underestimate the importance of

  1. Taking notes and
  2. Building small projects of your own

Practical tips to learn JavaScript for beginners

Furthermore, you can use a bunch of helpful learning strategies to speed up your learning.

Whether you’re learning JavaScript or another language, try these tips:

  • Focus on one language at a time:
    Don’t get distracted by another programming language you find intriguing. Learn your current one well before the next.
  • Finish every coding course you start:
    When you’ve started one, make sure you finish your online coding course before starting the next one. The lectures build on top of each other, so you want to make it to the last one. That’s where you’ll learn the “good stuff”, i.e. the more advanced lessons.
  • Keep your long-term goal in mind:
    For example, if you want to learn JavaScript to become a freelancer, keep your eyes on the prize. When you know what you want to do with coding in the future, you won’t run out of motivation along the way.

Since JavaScript uses variables, functions, and loops, it’s easier to learn JavaScript if you already know another programming language.

For example, I learned Python before I started learning JavaScript. With a good understanding of how programming languages work in general, I managed to learn JavaScript much faster than Python.

To speed up your learning even more, my #1 recommendation is to learn some Computer Science basics before coding.

How to find the best online JavaScript course?

As with pretty much any programming language, there are way more resources to help you learn JavaScript than you’ll ever need.

In fact, the biggest challenge is to find an online JavaScript course that will teach you everything you need to know to start building projects by yourself.

Therefore, you have two options here:

  1. Starting a 100% JavaScript-based course
  2. Choosing a course that teaches several tools including JavaScript

The first option is better if you already know what you want to achieve with coding in the future. If you’re 100% sure that you’ll use JavaScript as a Web Developer in the future, go ahead and choose a 100% JavaScript-based course.

The latter option is better if you’re just starting out with coding and web development. If that’s the case, you want to try out several tools and languages one by one. This will help you find the ones you like the most.

At the end of the day, the choice is yours.

But I can tell you this much: Most beginners are not quite sure what they want to achieve with coding and web development in the long run.

Therefore, I always suggest they learn the basics of more than one tool. It’s just easier to see which ones you really like working with before spending money on a course that focuses on a language that’s not your thing.
