Start Using ES6 Today
summary
ES6 features are usable now: block-scoped let/const fix closure loop bug so delayed callbacks see the right loop index, template strings allow embedded expressions and multiline HTML, arrow functions give concise callbacks and preserve this, destructuring pulls deeply nested fields into local variables and swaps values without temporaries, Sets/Maps provide unique collections and size/delete APIs, modules still require a bundler but transpilation via Babel + polyfill geo for older browsers and source maps let debuggers map back to original ES6.
