History of 2026-03-09 Create ranges of numbers in vanilla JS

Popular libraries like Lodash or Ramda have a function for that (in both cases, it’s called range), but how to do that concisely in vanilla JS? In case you’re wondering, both Lodash and Ramda use a while loop for this task; can we do better? (In this case “better” does not necessarily mean “faster”, but “shorter”, and – let’s be honest — “in a more clever/hackish/crazy way”.) It turns out that the answer is yes.
