To create a JavaScript array of integers in descending order, you can use the sort() method in combination with a comparison function that compares each element with its adjacent element and swaps their positions if they are out of order. Here’s an example:

let nums = [4, 2, 8, 1, 5];
nums.sort(function(a, b) {
  return b - a;
console.log(nums); // [8, 5, 4, 2, 1]

In the example above, the sort() method is called on the nums array with a comparison function that takes two parameters a and b. The function returns the result of subtracting b from a, which determines the order of the two elements being compared. If the result is negative, a comes before b; if the result is positive, b comes before a; and if the result is zero, the order of the two elements is unchanged.

By returning b - a, we are effectively sorting the array in descending order. The sorted array is then printed to the console using the console.log() method.
