My code does not work. the browser is telling me that arr[i] does not exist.
Am I missing something here? It’s been a long day and I’ve stared at this problem for way too long… I think my brain needs a reboot…
Please help!
Thanks in advance.
Best,
Julie
Your code so far
function steamrollArray(arr) {
var explored = [];
for(i=0; i<arr.length;i++){
var counter = 0;
while(arr[i].length>counter){
if (Array.isArray(arr[i])){
steamrollArray(arr[i]);
}// if
else{
explored.push(arr[i]);
}
counter++;
}// while
}// for i
return explored;
}// function
steamrollArray([1, [2], [3, [[4]]]]);```

I’ve edited your post for readability. When you enter a code block into the forum, remember to precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.
Your function returns a value. When you are calling it recursively you are not using that returned value, so your recursive call isn’t affecting you end result.
