84. Array.prototype.sort()

The code outputs:

[0, 2, 111, 1111, 999]
[0, 2, 111, 1111, 999]

a.sort() sorts the elements of the a array in place and returns the sorted array. Since b is assigned to the result of a.sort(), it also refers to the sorted array.

Therefore, both console.log(a) and console.log(b) output the same sorted array: [0, 2, 111, 1111, 999].
