JavaScript
1

Tell us what’s happening:

Your code so far


// Example
var ourArray = ["Stimpson", "J", "cat"];
ourArray.shift(); // ourArray now equals ["J", "cat"]
ourArray.unshift("Happy"); 
// ourArray now equals ["Happy", "J", "cat"]

// Setup
var myArray = [["John", 23], ["dog", 3]];
myArray.shift();

// Only change code below this line.
myArray.unshift("Paul", 35);

In myArray, you shift an element that happens to be an array.
May be you should as well unshift an other array and not just a string and a number.
Hope it helps !

This is the solution.
You need to pass the [] object:
myArray.unshift([“Paul”,35]);
