    Linked List Data Structure in JavaScript


    A linked list is a collection of items where each item points to the next one in the list. Because of this structure, linked lists are very slow when searching for an item at a particular index. An array, by comparison, has quick gets when searching for an index, but a linked list must start at the beginning, often called the "head", and loop through each item's next property until we arrive at the item. This makes gets in a linked list an operation that takes O(n) time.

    While gets might be slow in a linked list, it's other operations, like push and delete come with some great benefits we will see in the lesson.
