Скачать или смотреть JavaScript for Beginners #56 The splice() Array Method

Here, we will learn about the splice() array method in JavaScript. This can be used to delete items, add items into any array at a certain position, or replace items in an array with new ones.

Also, I forgot to state that you can add in an item without deleting something by using a delete count of 0. Here's an example:

const myArray = [1, 2, 4];
myArray.splice(2, 0, 3);
// [1, 2, 3, 4];

Last Example:
const currentFoods = ["Chicken", "Corn", "Rice", "Steak", "Potatoes", "Pasta", "Tacos", "Hamburger"];
const dislikedFoods = ["Pasta", "Corn"];
