var colors= ["red","blue"];

Friendly Hawk
var colors= ["red","blue"];
colors.push("yellow"); // for me lol... pls don't delete!
// use splice to insert element
// arr.splice(index, numItemsToDelete, item);
var list = ["hello", "world"];
list.splice( 1, 0, "bye");
//result
["hello", "bye", "world"]
Array.prototype.insert = function ( index, item ) {
this.splice( index, 0, item );
};const array1 = ['a', 'b', 'c'];
const array2 = ['d', 'e', 'f'];
const array3 = array1.concat(array2);var array = [0,1,3];
array.append(5);
console.log(array); // [0,1,3,5]var arr1 = ["Hello"," "];
var arr2 = ["World","!"];
var both = arr1.concat(arr2);
//both = ["Hello"," ","World","!"];
