  // Your code here
  arr.push(item);
  var removed = arr.shift();
  return removed;  // Change this line
}

// Test Setup
var testArr = [5,6,7,8,9];

// Display Code
console.log("Before: " + JSON.stringify(testArr));
console.log(nextInLine(testArr, 1)); // Modify this line to test
console.log(nextInLine([],1));
console.log(nextInLine([],5));
console.log(nextInLine([2],1));
console.log(nextInline(testArr,10));
console.log(nextInline(testArr[4]));

It is saying that nextInline is not defined, check capitalization

Also, the second of these calls will tell you that arr.push is not a function, because you don’t have an array as first argument, but a number, and so it is not possible to use array methods on numbers

It is not defined, because in these lines of code the name of the function is written incorrectly.

console.log(nextInline(testArr,10));
console.log(nextInline(testArr[4]));
