Trailing commas in Object/Array literal

Are trailing commas good style in javascript? I always use them for convenience.

var tom = {
  name: 'Tom',
  age: 20,
  friends: [
    'Jerry',
  ],
};

@felixsanz yup! we switched to Babel which removes trailing commas and we get the added benefit of cleaner diffs. https://github.com/airbnb/javascript#19.2
