Function map

Creates an array of values by running each element in collection thru iteratee. The iteratee is invoked with three arguments: (value, index|key, collection).

Many lodash methods are guarded to work as iteratee for methods like every, filter, map, mapValues, reject, and some.

The guarded methods are: ary, chunk, curry, curryRight, drop, dropRight, every, fill, invert, parseInt, random, range, rangeRight, repeat, sampleSize, slice, some, sortBy, split, take, takeRight, template, trim, trimEnd, trimStart, and words

function square(n) {
  return n * n;
}

map([4, 8], square);
// => [16, 64]

map({ 'a': 4, 'b': 8 }, square);
// => [16, 64] (iteration order is not guaranteed)

var users = [
  { 'user': 'barney' },
  { 'user': 'fred' }
];

map(users, 'user');
// => ['barney', 'fred']
