What is JS Exercises?

JS Exercises is an interactive JavaScript learning platform built for developers who learn by doing, not watching videos or reading walls of text.

Every concept is taught through hands-on coding. You write real JavaScript directly in your browser, run it against live tests, and get instant feedback.

No setup, no installs, just code!

Who is it for?

Whether you're picking up JavaScript for the first time or sharpening skills you already have, JS Exercises meets you where you are. Courses start from absolute zero and progress through to advanced topics like closures, DOM manipulation, async JavaScript and more.

- In-browser code editor with live test execution and instant feedback
