function: map


map(collection: Array, Object, iteratee: function): Array

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 iteratees 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`

Example(s):

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)

Params:

Name Type Attribute Description
collection The collection to iterate over.
iteratee The function invoked per iteration.

Returns:

Array
