Tell us what’s happening:
Describe your issue in detail here.

Your code so far

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

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

Your code:

// Setup
const myArray = [["John", 23], ["dog", 3]]; -> actual array

myArray.shift(); -> [["dog", 3]] -> actual array

// Only change code below this line
myArray.shift(); -> "[]" -> actual array

myArray.unshift(["Paul", 35]); -> [["Paul", 35]] -> actual array

You can see that, at one particular time in the code you get an empty array, try avoiding that.

Pd: Try to describe your problem in the next posts for a better understanding please.
