splice()

The splice method removes and returns a slice of items starting at the specified index:

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

const chunk = collection.splice(2);

chunk.all();

// [3, 4, 5]

collection.all();

// [1, 2]

You may pass a second argument to limit the size of the resulting chunk:

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

const chunk = collection.splice(2, 1);

chunk.all();

// [3]

collection.all();

// [1, 2, 4, 5]

In addition, you can pass a third argument containing the new items to replace the items removed from the collection:

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

const chunk = collection.splice(2, 1, [10, 11]);

chunk.all();

// [3]

collection.all();

// [1, 2, 10, 11, 4, 5]
