    You can use `.flat()` if using mordern browsers – Nick Parsons Aug 05 '19 at 04:23
  • If you want to write a function which converts an array of arbitrarily nested arrays of integers into a flat array of integers. e.g. [[1,2,[3]],4] -> [1,2,3,4]. ```function flatten(elements) { return elements.reduce((result, current) => { return result.concat(Array.isArray(current) ? flatten(current) : current); }, []); };``` Upvote this comment if this helped your work. –  Aug 05 '19 at 04:27
