🚀 Overview

javascript.info is the Modern JavaScript Tutorial, a detailed guide created in 2007 by Ilya Kantor to provide clear, high-quality explanations of JavaScript and browser technologies. It solves the problem of fragmented or outdated learning resources by offering a structured, up-to-date curriculum covering everything from basics to advanced topics like async programming, DOM manipulation, and web components.

It's built for developers at all levels—beginners starting from scratch, intermediate learners deepening their knowledge, and advanced users exploring browser APIs. The tutorial emphasizes practical understanding with real-world examples and tasks, making complex concepts accessible and free for everyone.

Ilya built it to democratize JavaScript education, and it's now open-source with community contributions, translations into many languages, and regular updates to keep pace with the evolving language.
