Javascript array sort with Reducer

This has been the most tricky/confusing javascript interview question for starters specially 😀

And this was my answer once which made interviewer shy: how the hell candidate will know if interviewer has speech recognition issue..

Btw, instead forloop, you can use "reducer" like this ⤵️

 let reducer = (acm, value) => { const nextIndex = acm.findIndex(i => value < i ); const index = nextIndex > -1 ? nextIndex : acm.length; acm.splice(index, 0, value); return acm; } // execution Ley arr = [ arr.reduce(reducer, []) will produce [1,2,3,4]

Let me know how you answered this kind of interviews

Thanks!
