5 * Returns a new list by plucking the same named property off all objects in
6 * the list supplied.
7 *
8 * `pluck` will work on
9 * any [functor](https://github.com/fantasyland/fantasy-land#functor) in
10 * addition to arrays, as it is equivalent to `R.map(R.prop(k), f)`.
11 *
12 * @func
13 * @memberOf R
14 * @since v0.1.0
15 * @category List
16 * @sig Functor f => k -> f {k: v} -> f v
17 * @param {Number|String} key The key name to pluck off of each object.
18 * @param {Array} f The array or functor to consider.
19 * @return {Array} The list of values for the given key.
20 * @see R.project, R.prop, R.props
21 * @example
22 *
23 * var getAges = R.pluck('age');
24 * getAges([{name: 'fred', age: 29}, {name: 'wilma', age: 27}]); //=> [29, 27]
25 *
26 * R.pluck(0, [[1, 2], [3, 4]]); //=> [1, 3]
27 * R.pluck('val', {a: {val: 3}, b: {val: 5}}); //=> {a: 3, b: 5}
28 * @symb R.pluck('x', [{x: 1, y: 2}, {x: 3, y: 4}, {x: 5, y: 6}]) = [1, 3, 5]
29 * @symb R.pluck(0, [[1, 2], [3, 4], [5, 6]]) = [1, 3, 5]
