function nextInLine(arr, item) {

  // Only change code below this line

  

  return item;

  // Only change code above this line

  arr.push(item);

  return arr.shift();

}

// Setup

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

// Display code

console.log("Before: " + JSON.stringify(testArr));

console.log(nextInLine(testArr, 6));

console.log("After: " + JSON.stringify(testArr));

Your code works, but the order seems to be whats wrong. When a function is called it goes through each line of code you write, top to bottom. So in order the function you wrote in the code you gave reads :

function nextInLine(arr, item) {
   // first > return item;
   // second > arr.push(item);
   // third > return arr.shift();
}

The lesson also tells you to only change code on a specific set of lines. If you deviate from that, you might put your code in the wrong order.

Hopefully this can help ya figure out the problem!

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

Note: Backticks (`) are not single quotes (’).
