.repeat() in String

I came across a coding question where I was required to repeat # for n number of times. e.g. ######

Thanks to this particular question, I was able to find out that such an API existed and certainly has helped me with the question.

One example usage would be (from MDN):

const mood = "Happy! ";

console.log(`I feel ${mood.repeat(3)}`);
// Expected output: "I feel Happy! Happy ! Happy! "

And for my particular case, to repeat # 6 times, all I needed to do was:

console.log(`${"#".repeat(6)}`);
// Expected output: "######"
