Tell us what’s happening:

Your code so far


function nextInLine(arr, item) {
  // Your code here
  
  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));
nextInLine([], 5);
nextInLine([], 1);
nextInLine([2], 1);
nextInLine([5,6,7,8,9], 1);

I don’t understand what this problem is trying to do, use it in the above scenario

Think about how you would add an element to an array.
And then think about how you will remove the first element from that array.
