# prepend()

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

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



// [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');


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