Notes on converting CoffeeScript to ES6

Some quick notes on hand-converting from CoffeeScript to ES6/ECMAScript 2015 (e.g. for use with bablejs):

  • add 'use strict'; to beginning of file
  • add let before new variable assignments, or const if they are constant
  • add semicolons to end of statements (optional)
  • add commas between elements of multi-line array literals
  • add parenthesizes around function calls
  • add braces around blocks
  • replace (args) => with (args) => { arrow functions
  • replace for x in a with for (let x of a) {

Gradle vs Maven, >2x faster build times
(note: mostly fixed by removing 'clean' from gradle defaultTasks)
