Editor's intro

Editor's intro

JavaScript runs in every browser, most web toolchains, and a surprising number of servers and desktop apps. It also carries decades of history, so beginner resources vary wildly in quality. This feed sticks to material that teaches modern JavaScript — let and const, modules, async/await — and explains the older parts only where you'll actually run into them.

Pair one structured course with javascript.info as your reference. Once the language feels familiar, the intermediate picks cover how JavaScript executes: scope, closures, the event loop, and prototypes. The advanced material is for people writing libraries or chasing performance. If your goal is building websites, follow Web Development too.

The Modern JavaScript Tutorial

javascript.info Articles Free

The Modern JavaScript Tutorial at javascript.info is the resource we'd pick if we could only keep one. It starts from absolute basics but never simplifies to the point of being wrong, and each chapter ends with small exercises that have worked solutions. It is also unusually current: it teaches the language as it's written today rather than as it was in 2012. Work through Part 1 in order, then treat Parts 2 and 3 as a reference for the browser and advanced topics.
