1Which of the following methods is used to return the last element of an array?Review Laterpop()slice()splice()reduce()
Solution
The method used to return the last element of an array is pop(). Here's how it works:
- The pop() method is called on an array.
- This method removes the last element from the array.
- It then returns that element.
So, if you have an array like this: let array = [1, 2, 3, 4, 5]; And you call array.pop(); The method will return 5, and the array will then be [1, 2, 3, 4].
