Tell us what’s happening:
Hi guys,can someone explain this to me. I really don’t get it

Your code so far

function nextInLine(arr,ray) {
  
  // 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));
