The Copilot is not always offering the best or the most up-to-date code there is, but it offers a great way to get a glimpse of the code that some other people wrote at a point in time, when they were faced with a similar issue.

Once you install it in your text editor - I use it in VS Code - it will offer suggestions as you’re coding, and you can use those suggestions by pressing the TAB key to use the offered suggestion. Touted as “Your AI pair programmer”, Github’s Copilot is a pretty cool piece of software. When combined with Quokka or RunJS, it makes for a very nice learning setup.

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. 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. There’s no point in doing the same thing over and over again.Īsking 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. Always ask yourself: How do I get better? This app frees up our brains to do other stuff, such as, write more JavaScript code.

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. Use vĪn alternative to Quokka is a standalone app called Runjs. Here’s an example of what happens when you type in a simple for loop:īecause Quokka outputs right inside the JavaScript file you’re editing, it saves time, making us more productive in our JavaScript learning. Once you run it, a new JS file will open in the console.

press CTRL SHIFT p to start the command palette.

To install it on VS Code, just visit this URL and click the install button. Here is a screenshot of it used in practice. The wallaby.js team released this awesome tool. Using Quokka.js to learn JavaScript faster

Always ask yourself: How do I get better?ġ. Here is a list of things you can do to make that learning even faster and easier. There are many ways to improve how you learn JavaScript and how you retain that knowledge. In this article, we’ll look at practical ways of improving the way we learn JavaScript.
