Is there a way to make JavaScript read strings as strings when multipying by numbers?

I am (using JavaScript) trying to get an output of 50 dashes as a banner like this:

"————————————————–"

I have so far tried the following:

let a = []
for (var i = 0; i < 50; i++) {
  a.push("-")
}

console.log(...a)

and

console.log("-" * 50)

These do not work, as in the first one, there are spaces in between the dashes.
The second one returns NaN, which is not what I need either.

The regular way I used to do this in Python was:

print("-" * 50)

This gave the perfect result of "—————————————————-".

The print() function being Python’s equivalent of console.log().

However, this does not work in JavaScript, as said before.

I also figured out that this does not work due to the fact that the string is parsed as a number.

Is there a way to achieve the "—————————————————-" banner in JavaScript without typing it manually, or is there a way to make sure that "-" is not parsed as a number?
