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

Stack Overflow Asked by PythonCreator on October 1, 2020

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++) {



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?

No, javascript lack of that feature. But you could use repeat() on ECMAScript6:

if you want to use an Array:

let a = Array(50).fill('-').join('')
