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.
var myArray = myArray.unshift(["Paul",35]);

alert(myArray);

#2

they gave you an example of how to use unshift in the code
ourArray.unshift("Happy");

So just change your new line of code to look the same…


#3

This line is not good ?

var myArray = myArray.unshift([“Paul”,35]);

I used the example you’re telling me


#4

your line
var myArray = myArray.unshift([“Paul”,35]);
sample line
ourArray.unshift("Happy");

Do you see how yours is different? You need to remove the ‘var myArray =’ part.
