JS in-string variables

We all love JS, don't we? Yes, we do. But, unfortunately, JS does not allow us to insert variables inside a string. We must close our quotes, concatenate with a + operator, and live our lives. What this tiny script does is replace anything inside #{ } for a variable. Ruby users know what this is.

Example

Let's say, you have two variables:

var mood = "nice";

const isPrime = (n) => {
	let max = Math.floor(Math.sqrt(n));

	for (var i = 2; i <= max; i++) {
		if (n % i == 0) {
			return false;
		}
	}

	return true;
