Tell us what’s happening:

I’m trying to figure out what I am missing in my code

Your code so far

function nextInLine(arr, item) {
  arr.push(item);// Your code here
  arr.shift(item);
  return item;// 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));
