# # `prepend()`

The prepend method adds an item to the beginning of the collection:

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

    collection.prepend(0);

    collection.all();

    //=> [0, 1, 2, 3, 4, 5]

You may also pass a second argument to set the key of the prepended item:

> Pro tip: Order of properties in objects is not guaranteed in JavaScript; When calling prepend with a key, the Collection uses the underlying `put` method behind the scenes. This is only supported so that collect.js have the same api as Laravel Collections.

    const collection = collect({
      product: 'iPhone 6s',
    });

    collection.prepend('Apple', 'brand');

    collection.all():

    //=> {
    //=>   brand: 'Apple',
    //=>   product: 'iPhone 6s',
    //=> }
