Tell us what’s happening:

Your code so far


function nextInLine(arr, item) {
  // Your code here
  var remove = arr.shift(arr[1]);
  return remove;  // Change this line
}
nextInLine([1,2,3,4,5])
// 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));

shift() doesn’t take parameters, and remove the first element of the array (which, by the way, is the item at index 0)
you are missing the first part:

Add the number to the end of the array, then remove the first element of the array.

you are not adding item at the end of the array
