Repeat a string multiple times in an assignment

Question

With numbers you can multiply a number a certain number of times using the following code:

var y = 10;
var x = y * 3; // 30

Is there a way to do the same with strings with native methods?

var y = "test ";
var x = y * 3; // test test test

Or if not is there a succinct way to do this in a single line?

The duplicate can be applied to any string, not just single character strings. — Felix Kling, Nov 18 '19 at 22:55

You could do:

var y = "test ";
y = y.repeat(3);

And this would give you "test test test "

What would be "string"*3 in Python, can be done with "string".repeat(3) in Javascript. That appears to be what you want.
