You need to be more specific than just saying you are stuck. What exactly is your question regarding this challenge?

Here you have a function named nextInLine that takes 2 parameters, one is an array and the other just an item.

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

They are asking you to add item to the end of the arr (which is an array), here’s a hint, what JavaScript method do we use to add elements to the end of a given array? Probably you saw that in previous lessons, you can go back or look for it on Google. Then you have to remove the last element from the same array, there’s a method for that as well. Look something like “remove element from array” on Google and you will find the answer.
