Ruby like ranges in JavaScript?

Question

In ruby you can specify a range like:

(1...10).each do |num|
  puts num
end

or

(1...15).each do |num|
  puts num
end

is there a way to do something similar in JS without having to build a function that defines a range, such as:

function myRange() {
  let x = [1,2,3];
  return x;
}

Also the question on stack overflow "Does JavaScript have a method like “range()” to generate a range within the supplied bounds?" is the opposite of this question.

without <- keyword

You can create an array like this: `Array.from({length: 15}, (_, index) => index + 1)`, then `.forEach((value) => console.log(value))`. — Sebastian Simon, Apr 14 '18 at 17:17
@Xufox I saw that question but it is the opposite of my question. Its asking for a function. — Ghoyos, Apr 14 '18 at 17:20
I’m not sure why you wouldn’t want a function. Why does that matter? — Sebastian Simon, Apr 14 '18 at 17:22

Since it seems like your question is specifically whether there is an built-in method to do this and you don't accept any workarounds, the answer is no, there is no built-in js method to do this.
