Shuffle the array using JavaScript's built-in Math object and its random () method, which returns us a random value from zero to one, but not including 1. From an array of elements, we create pairs - a random number and an array element. After that we sort the new array of pairs. Sorting is performed by newly generated random numbers. Because of this, the original elements get mixed up. After that, we iterate over the new array and return only the "old" elements. They will be mixed in the new array.
