Stand in Line let removed = arr.shift([0]);

Tell us what’s happening:

Hi guys!

Hope you’re doing well.

If someone know, can you please explain why my code is not going through? It seems that on it works.

Your code so far

function nextInLine(arr, item) {
  // Your code here
  let removed = arr.shift([0]);
  return removed;  // Change this line

// Test Setup
var testArr = [1,2,3,4,5];

// Display Code
console.log("Before: " + JSON.stringify(testArr));
console.log(nextInLine(testArr, 6)); // Modify this line to test
console.log("After: " + JSON.stringify(testArr));

Link to the challenge:

your function takes an argument arr, which you use in let removed = arr.shift([0]);, and that’s ok

but consider what your line testArr.push(item); does. What happens if you call for example nextInLine([], 1);?

ah, arr!!! =)

I needed to use arr =) thank you!
