re: How to create range in Javascript VIEW POST

FULL DISCUSSION
 

It rather depends, Jason, on what you mean by cooler.

If you only needed range to handle approx. 6000 iterations then I think a recursive range function is pretty cool, but slow:

const range = (s,e) => (s === e) ? [s] : [s, ...range(s+1,e)]

But, if you need a much bigger range and fast executuion then do something like this:

const range = (s=0,e=10,r=[]) =>
  {while(e >= s){ r.push(s); (e>=s)? s++ : s--; } return r }

And if you don't like the arrow function, then it's easy to convert to a standard es5 style function.
