How to change the values of elements of an array at once in javascipt

Question

I want to change the values of elements of an array to the same number. For eg:

let arr = [1,2,3]
arr[0] = 0;
arr[1] = 0;
arr[2] = 0;

Is there any other method to do this?

Answer 1

Try Array.fill:

let arr = [1,2,3];
arr.fill(0);
