ECMAScript 6 Katas
summary
A hands‑on workflow that teaches ES6 by writing tests: ES6 Katas pairs browser Babel transpilation with a TDD editor at tddbin.com and currently contains 61 katas. Live examples show import must be top‑level, named and default imports, aliasing, and the iterator protocol (Symbol.iterator, next returning {value, done}), with tests driven until everything is green. The stack runs in the browser, one user reports developing tests there then pasting production code into a repo.
