Help me with the Steamroller Intermediate Algorithm please. :)

Tell us what’s happening:
Hi, so the question was to flatten/steamroll the array. And I know there are numerous answers in the hint section but I’m wondering why my answer isn’t working.
Thanks in advance :slight_smile:

Your code so far

var tab=[];
function steamrollArray(arr) {
  // I'm a steamroller, baby

for(let i=0;i<arr.length;i++){




  return tab;
steamrollArray([[["a"]], [["b"]]]);

Link to the challenge:

it’s an interesting approach, though I’d really advise against it

using a global variable like that is a bit nasty, at the very least it should be captured in another function body or something

If steamRollArray is called multiple times, e.g. steamrollArray([[["a"]], [["b"]]]); steamrollArray([[["c"]], [["d"]]]); what do you expect to happen?

Aha, It’ll start saving all the values from both the function calls. Thank you @gebulmer :slight_smile:
