(Potential) Groupon Javascript Styles, based on https://github.com/airbnb/javascript

base.js

{
  // babel-style base rules
  "extends": "airbnb/base",
  "rules": {
    // This allows things like `reduce((a, b) => a + b)`
    // Not 100% sure if that's worth the potential cost of badly named identifiers
    "id-length": 0
  }
}

legacy.js

{
  // ES5-style base rules
  "extends": "airbnb/legacy",
  "rules": {
    // This allows things like `reduce(function(a, b) { return a + b; })` and `var _ = require('lodash')`
    "id-length": 0,
    // With unused/redefine tracking, no need to force vars to be at the top
    "vars-on-top": 0,
    // In legacy mode, we can't depend on babel to insert `'use strict'` for us
    "strict": [2, "global"],
    // Without default parameters, things like `options = options || {}` are kind of useful
    "no-param-reassign": 0
  }
