In python you can do:
arr = [1,2,3] * 3 print(arr)
Is there a concise way of doing this in java script? The best I can think of is something like:
let arr2 = [...arr, ...arr, ...arr]
but if I wanted to do this 100 times it would be impractical. In python I would just multiply it by 100.
You could do this:
var repeated = .concat(... new Array(100).fill([1, 2, 3]));
That creates an array of a given length (100 here) and fills it with the array to be repeated (
[1, 2, 3]). That array is then spread as the argument list to
Oh wait just
var repeated = new Array(100).fill([1, 2, 3]).flat();
would be a little shorter.
