pop array index to end of array javascript code example
Example 1: remove from array javascript
let numbers = [1,2,3,4]
// to remove last element
let last_num = numbers.pop();
// numbers will now be [1,2,3]
// to remove first element
let first_num = numbers.shift();
//numbers will now be [2,3]
// to remove at an index
let number_index = 1
let index_num = numbers.splice(number_index,1); //removes 1 element at index 1
//numbers will now be [2]
//these methods will modify the numbers array and return the removed element
Example 2: take off element form end of array
