JavaScript the Cute Parts
summary
Concrete ES6 fixes and patterns that change day-to-day code: avoid var and use const over var (const prevents mutation errors shown), prefer let only when you must, replace arguments with rest parameters so you get a real array and can reduce, use spread to call or merge arrays, default parameters to extend APIs safely, for...of plus destructuring to get index and value, implement Symbol.iterator and generators to make custom classes iterable, and remember arrow functions capture lexical this so don’t use them as class methods.
