Let's say I want to concatenate a certain string, e.g. "#", a certain number of times, e.g. n=5. (the number of times, n, is variable.)
So for n=5, we would get: ##### but for n=2, we would get: ## etc.
Is there a way to do this without using a loop?
You can do it by using String.prototype.repeat(). According to MDN
The
repeat()method constructs and returns a new string which contains the specified number of copies of the string on which it was called, concatenated together.
It takes a count parameter as it's the only argument which is
An integer between
0and+Infinity, indicating the number of times to repeat the string.
And returns
A new string containing the specified number of copies of the given string.
let str = "#";
let newStr = str.repeat(5);
console.log(newStr);You can use string.repeat(count):
console.log("#".repeat(5));
