Replit allows you to write and run code in the browser in an IDE (integrated development environment). You don’t need to download anything to get this working. Log in with GitHub, choose a language, name your Repl, and start coding.

You can either choose HTML, CSS, JS or Node.js as your language when writing JavaScript. Your output will be displayed on the right hand side of the IDE.


Stackblitz is an IDE which has a similar look and feel to VS Code. From here you can build websites and synchronise your code with a GitHub repository.

Stackblitz doesn’t save your work automatically so remember to click Save in the top left after you write a chunk of code.

VS Code
