Pop

The pop method removes the last element from an array and returns that element. This method changes the length of the array.

Here's the syntax for using pop:

array.pop();

For example:

let arr = ["one", "two", "three", "four", "five"]; 
arr.pop(); 

console.log(arr); 

// Result: ['one', 'two', 'three', 'four']

You can also use the pop method in conjunction with a loop to remove all elements from an array. Here's an example of how you might do this:

while (array.length > 0) {
  array.pop();
}

console.log(array); // Result: []
