Basic JavaScript: Manipulate Arrays With push()
An easy way to append data to the end of an array is via the push()
function.
.push() takes one or more parameters and “pushes” them onto the end of the array.
var arr = [1,2,3];
arr.push(4);
// arr is now [1,2,3,4]
Push [“dog”, 3] onto the end of the myArray variable.
Correct Solution:
var ourArray = [“Stimpson”, “J”, “cat”];
ourArray.push([“happy”, “joy”]);
// ourArray now equals [“Stimpson”, “J”, “cat”, [“happy”, “joy”]]
// Setup
var myArray = [[“John”, 23], [“cat”, 2]];
// Only change code below this line.
myArray.push([“dog”, 3]);
Nowhere in this lesson does it show how to add an array into an existing group of arrays! The previous Arrays lessons didn’t even touch on this. How is a person supposed to learn when not even the correct examples are given?
