array insert remove code example

Example 1: splice()

/"removes any number of consecutive elements from anywhere in an array."/
let array = ['today', 'was', 'not', 'so', 'great'];

array.splice(2, 2);
// remove 2 elements beginning with the 3rd element
// array now equals ['today', 'was', 'great']

Example 2: remove element 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
