Basic JavaScript - Stand in Line

JavaScript
1

Tell us what’s happening:
help " nextInLine([], 5) should return a number."
and
nextInLine([], 1) should return 1

// running tests

nextInLine([], 5)

should return a number.

nextInLine([], 1)

should return

1

// tests completed // console output Before: [1,2,3,4,5] 1 After: [2,3,4,5,6]

Your code so far

function nextInLine(arr, item) {
  // Only change code below this line
  
 testArr.push(item);
 const removed = arr.shift();
  return removed;
  // Only change code above this line
}

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

// Display code
console.log("Before: " + JSON.stringify(testArr));
console.log(nextInLine(testArr, 6));
console.log("After: " + JSON.stringify(testArr));
