JS Help With Queues and Arrays

When it comes to removing the first item of an array I think of the .shift() method and the .push() method to add to the end. Other than that I don't know what to do because that isn't discussed at all on this challenge.

On the return line is it asking me to do something like this?

function nextInLine(arr, item) {

  return arr + item; 
}

No, that would not work. That's not really how you add a value to an array and the task is to only return the removed item, not the entirety of the array + the item added on.

You are on the right track with shift and push. if you use push on the array you can insert the item value at the end, this accomplishes the first step of the task.

One thing you might not know about the shift method is that in addition to removing the first item of an array it also returns said item. This means that you can assign the result of running arr.shift() to a variable (or a return statement) in order to get a copy of the item that was removed.

I feel that should be enough hints. If you are still stuck you can post again and I'll either just post the solution or answer your question if you have other specific questions.

I got it

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


  arr.push(item);
  var removed = arr.shift();

  return removed;  // 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));

By the way, why does my code always come out orange?

add the name of the syntax you're using after the code marks.

i.e. ```JavaScript

Edit: Edited after receiving valuable pro-tip to escape the back-tick

That's great.

When using code formatting on this forum you have to type the name of the language you are pasting in after the three backticks that indicate the start of the code block.

So the first line of the code block should look like this:

```JavaScript

If you don't specify a language then everything will be highlighted in orange.

Also Michael Davis pro tip for the future, you can escape the various code formatting options on this forum using \ as an escape character. By using that you can show off the three backticks properly without them being misunderstood by the forum software.
