Add Items to an Array with push() and unshift()

Add Items to an Array with push() and unshift()

• Just like the example given, use the .unshift() method on the array to add elements to the start of the array and use the .push() method to add elements to the end of the array.

Solution:

function mixedNumbers(arr) {
  // change code below this line
arr.unshift('I',2,'three');
arr.push(7,'VIII', 9);
  // change code above this line
  return arr;
}

// do not change code below this line
console.log(mixedNumbers(['IV', 5, 'six']));
