Try writing the same thing without a computer why don't ya. As an interviewer I can see why you would want to force someone to jump through arbitrary hoops lik

  No need for the snark. There is still way more ES5 code being written than ES6. The point is demonstrating knowledge of closures and variable lifecycle, the how is irrelevant. I replied specifically because he said "I don't see the problem" - if you start with ES6 I can imagine it doesn't look like a problem at all.

    If you can explain why that ES6 code doesn't share the problem, that's as good at demonstrating the knowledge you're looking for as restricting the candidate to an older subset of the language. I would accept "okay, now explain what distinguishes arrow functions from regular functions" as a follow-up question, but "now do it in ES5" seems arbitrary. In fact I would argue it's important that if the candidate shows practical knowledge of ES6 you need to make sure they also grasp the actual semantics (i.e. they won't rely on implementation details of Babel and run into errors in native ES6 environments). That said, if you are hiring for a dedicated frontend developer role, the majority of JS you write will have a build step. If it has a build step, you should use modern tooling. If you use modern tooling, you might as well include Babel to make the developers' lives less of a pain.
