Describe your issue in detail here.

Your code so far

function nextInLine(arr, item) {
  // Only change code below this line

  arr.shift()
  return item;
  // Only change code above this line
}

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

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

:balloon: Hi, welcome to the forum!
We see you have posted some code but did you have a question?

3

I have not asked any question yet in this type of forum and yes I have a question too that how this code is taking the sequence of counting cause i didnot put the 6 but it gives the correct answer.

4

The code you posted is not passing the tests. What do you mean by

5

it’s passing but i didn’t understand the code.

6

I’ve just run the code you posted.
The test result is:

// running tests
nextInLine([2], 1) should return 2
nextInLine([5,6,7,8,9], 1) should return 5
After nextInLine(testArr, 10), testArr[4] should be 10
// tests completed

Not passing. It is not corect solution for this step for a couple of reasons. That’s why I am a bit confused when you are saying that it is giving correct answer

7

Sorry,i was wrong it is not passing my test . and i can’t understand this thinggg.
Helpppp!!!
is this the correct code that you posted???

8

no it is not. It is not code, it is just results of testing your code from the console.
And we’re not posting solutions here

Can you elaborate what exactly you don’t understand? Instructions? Some part of code? Something else?

9

Help me tu understand what excatly we have to do in this task.

You are not far from the correct answer.

Why are you pushing 6 to the array? What if the user inputs a different value for item?

You are not supposed to return item. You are asked to return the value of the number which is removed from the array, not the number which was added.

TOP TIP: arr.shift() not only removes the first item from an array but also returns the removed value. So you could combine your return statement with this method.

I am a little confused here but understood the code .
Thank you
