Stand in Line Help

Tell us what’s happening:
I don’t know what to do next.

Your code so far


function nextInLine(arr, item) {
  // Your code here
  function nextInLine([], num) {
    
    nextInLine([], 5);
    nextInLine([], 1); // should return 1
    nextInLine([2], 1); // should return 2
    nextInLine([5,6,7,8,9], 1); // should return 5
    
  }
  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, 10)); // Modify this line to test
console.log("After: " + JSON.stringify(testArr));
