how to use array.splice( code example

Example 1: remove element from array javascript

let fruit = ['apple', 'banana', 'orange', 'lettuce']; 
// ^^ An example array that needs to have one item removed

fruit.splice(3, 1); // Removes an item in the array using splice() method
// First argument is the index of removal
// Second argument is the amount of items to remove from that index and on

Example 2: 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
