random()

The random method returns a random item from the collection:

const collection = collect([1, 2, 3, 4, 5]);

collection.random();

// 4 (retrieved randomly)

You may optionally pass an integer to random to specify how many items you would like to randomly retrieve. A collection of items is always returned when explicitly passing the number of items you wish to receive:

const threeRandom = collection.random(3);

// Collection { items: [ 5, 3, 4 ] } (retrieved randomly)

const oneRandom = collection.random(1);

// Collection { items: [ 3 ] } (retrieved randomly)

oneRandom.all();

// [3]
