ES6 Tutorial

This is a comprehensive, book-style tutorial that teaches modern JavaScript beginning with ES6 and continuing into later additions to the language. It introduces core syntax like let/const, template literals, destructuring, modules, and classes before moving to promises, generators, async/await, proxies, and symbols. Each chapter mixes explanation with concise examples, emphasizing why a feature exists and how to use it idiomatically. The material serves both as a learning path and a reference you can revisit when you forget specific details or edge cases. Practical sections cover collections, iterators, typed arrays, and internationalization, tying abstract concepts to real use. The tutorial is widely used by engineers preparing for interviews, onboarding to modern JS codebases, or refreshing knowledge after time away.
