Stand in Line not correct

Tell us what’s happening:
Not sure what I’m doing wrong here… I added the push and shift lines, but still getting errors

Your code so far

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

Link to the challenge:

Remember when you return from a function, everything after it cannot be reached. You’ve got two return keywords.

Also, make sure you understand what you are returning. Are you supposed to return item or something else?


I see a few things…

You seem to be clear that using push and shift will alter the array as needed.

As @zapcannon99 stated once your program hits a return statement the function ends so anything after a return will be ignored.

You are pushing a number 6 onto your array instead of whatever number is passed to your function (item). Your function would only work if the number just happened to be a 6.

You should refer to the array and number by their “local” names in the function - arr and item

// function takes two parameters, 
// an array locally named arr 
// and a number locally named item
function nextInLine(arr, item) {
      //Put item onto end of arr
      //take first element off of arr 

      return  ?  // return the element removed from arr

// Test Setup
var testArr = [1,2,3,4,5];

// passing an array and a number to function nextInLine
console.log(nextInLine(testArr, 6)); // output should be 1
console.log("After: " + JSON.stringify(testArr));  // [2,3,4,5,6]

I think you’re very close to a solution. Good luck
