Your code so far
function nextInLine(arr, item) {
// Only change code below this line
nextInLine.push(item);
nextInLine.shift(item);
return item;
// Only change code above this line
}
// Setup
var testArr = [1,2,3,4,5];
// Display code
console.log("Before: " + JSON.stringify(testArr));
console.log(nextInLine(testArr, 6));
console.log("After: " + JSON.stringify(testArr));

The challenge asks that you
The nextInLine function should then return the element that was removed.
While your function is returning the item its receiving as argument
return item;
Hope this helps
