Stand in Line Random Question

Tell us what’s happening:

So, this is a random question that seems really dumb asking but I think it will help be further understand functions.

Do all functions require a variable?

Your code so far

function nextInLine(arr, item) {
  // Your code here
  arr.push(item);
  var removed = arr.shift();
  return removed; // 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));

Link to the challenge:

Like,
var randomVar = someRandomThing.

Just wondering if all functions needed a variable defined inside of them for it to be a function.

I’m not sure if I explain that correctly but that’s the closest I can get to explaining what I mean.
