If you were to assign the return value of the pop() method, the output would be slightly different, displaying the item that was removed instead of the remaining items in the array: var items = var result = items.pop() console.log(result) // 4 JavaScript shift() Method: Remove First Item from Array

In this example, you'll notice that 4, the last element in the array, is removed from the array, and only the first three items are left: var items = items.pop() console.log(items) // 1, 2, 3

JavaScript's pop() method removes the last item in an array. If you were to assign the return value of the push() method, the output would be slightly different, displaying the item that was appended to the end of the array instead of all the elements: var items = var result = items.push(4) console.log(result ) // 4 JavaScript pop() Method: Remove Last Item from Array Here, the number 4 is appended to the end of the array, changing the number of array elements from three to four: var items = items.push(4) console.log(items) // JavaScript's push() method appends an item to the end of an array. JavaScript push() Method: Append New Item to Array

JavaScript arrays are extremely useful for assigning sequential collections of data.
