Tell us what’s happening:

Your code so far


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

  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));

+ is for addition or joining strings. You can’t add things to an array with it.

JavaScript has methods designed specifically to do what the task asks for: look at thr documentation for shift, unshift, push and pop - two of those will be useful.
