console.log(randomElement);

// This function takes an array as an argument and returns a random element from it. The Math.random() function generates a random number between 0 and 1 (exclusive). We multiply this number by the length of the array to get a random index within the bounds of the array. We then use Math.floor() to round down to the nearest integer, which gives us a valid index for the array.
function getRandomElementFromArray(arr) {
  return arr[Math.floor(Math.random() * arr.length)];
}
