I already wrote the code below and it
worked very well, but the system
does not pass me to the next challenge
I even tryed the code in replit and worked
well.

Your code so far


// Setup
const myArray = [["John", 23], ["dog", 3]];

myArray.shift();

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

console.log(myArray);
