Here, the numbersCopy array will have all its positions with value ([0,0,0,0,0,0]). We can also pass the start index that we want to fill the array with, as follows:

numbersCopy.fill(2, 1); 

In the preceding example, all the positions of the array will have the value 2, starting from position 1 ([0,2,2,2,2,2]).

It is also possible to pass the end index that we want to fill the array with:

numbersCopy.fill(1, 3, 5);
