Stand in Line nextInLine([5,6,7,8,9], 1) should return 5

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));
nextInLine([], 5);
nextInLine([], 1);
nextInLine([2], 1);
nextInLine([5,6,7,8,9], 1);
