In this article, we’ll look at practical ways of improving the way we learn JavaScript.

There are many ways to improve how you learn JavaScript and how you retain that knowledge.

Here is a list of things you can do to make that learning even faster and easier.

#1. Using Quokka.js to learn JavaScript faster

The wallaby.js team released this awesome tool.

Here is a screenshot of it used in practice.

Quokka in use

To install it on VS Code, just visit this URL and click the install button.

After installation:

  1. press CTRL SHIFT p to start the command palette
  2. type Quokka into it
  3. run the New JavaScript file command

Once you run it, a new JS file will open in the console.

Type some JavaScript into it!

Here’s an example of what happens when you type in a simple for loop:

Quokka outputs right inside VS

Because Quokka outputs right inside the JavaScript file you’re editing, it saves time, making us more productive in our JavaScript learning.

#2. Use runjs.dev

An alternative to Quokka is a standalone app called Runjs.

It’s amazing how this little app can significantly improve your productivity, by saving all the time and effort we would invest into “parsing” our own code. This app frees up our brains to do other stuff, such as, write more JavaScript code.

3. Always ask yourself: How do I get better?

There’s no point in doing the same thing over and over again.

Asking myself the question of “How do I get better at JavaScript?” has led me to understanding that I need to catalog all my JavaScript knowledge. This, in turn led me to writing down the things I know, and ultimately, lead to me writing and self-publishing a series of books on JavaScript.

Side note: This book series titled A Better Way to Learn JavaScript, available as individual copies or as a bundle of all 5 books in the series, on Leanpub.

These books are full of code snippets that you can run and test. When combined with Quokka or RunJS, it makes for a very nice learning setup.
