  var arr = [2];
  arr.push(item);
  
  var removed = arr.shift();
  
  return removed // Change this line
}

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

console.log("Before: " + JSON.stringify(testArr));
console.log(nextInLine([4], 2)); // Modify this line to test
console.log("After: " + JSON.stringify(testArr));

doing this you are overwriting the function parameter arr, so doesn’t matter what argument you get, it gets overwritten

just use arr directly

Funnily enough, I’ve just worked through this exercise again after a break from coding to look after my new son. I thought it when I first did the exercise and I still think it now having had to think about it again this morning - it’s a pretty esoteric question given the lessons that have come before it and I’m not surprised people find it confusing.
