Usage

For more use-cases see the tests

var pickItems = require('pick-items');

// API
// - pickItems(array[, count/options])

By default omit the quantity to retrieve a set with a random length:

pickItems([1, 2, 3, 4, 5]);
// => [2, 5]

Can optionally specify the quantity to retrieve:

pickItems([1, 2, 3, 4, 5], 3);
// => [1, 2, 4]

Can optionally shuffle the new array or not:

pickItems([1, 2, 3, 4, 5], { count: 3, shuffled: true });
// => [3, 1, 5]
