      Nifty trick I've seen around and heard about on @syntaxfm - Array.from({ length: n }) gives you an array full of undefined that you can use in place of traditional for loops. Super handy for executing something a set number of times!pic.twitter.com/AyUK8HtETe

      Keep in mind that this would create a HOLEY_ELEMENTS array so it would not be as optimal to iterate over as a plain for loop. So for >1000 it’s an awesome solution, but if you were to do larger might want the uglier code

      Yep - definitely a good point. I definitely consider this a quick and dirty convention. If I'm working on something more production ready or crucial, I typically reach for Lodash's `times` method: https://lodash.com/docs/#times . It's implemented a `while` loop under the hood.

      @mathias I just looked over _ times and it looks like it makes an array with holes for the results, is that because the resizing that push would cause would be bad? Also is what I said above wrong or not getting the point? Just don’t want to give bad advice

      `Array.from({ length: n })` indeed results in a “holey” array in current @v8js. We might be able to avoid that in some cases in the future, though: https://bugs.chromium.org/p/v8/issues/detail?id=7557 … More info on elements kinds: https://mths.be/v8ek
