Tell us what’s happening:

Your code so far


function nextInLine(arr, item) {
  // Your code here
  
  
  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));

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

The nextInLine function should then return the element that was removed.
