Basic JavaScript - Stand in Line

[mikemcmullon]

Tell us what’s happening:
Describe your issue in detail here. The code for the first 2 nextInLine passes. The rest do not, and I do not know why. I found the instructions for this challenge to be extrremely confusing. I’m probably making something simple too complex.

Your code so far

function nextInLine(arr, item) {
  // Only change code below this line
  arr.push(6);
  arr.shift();
   return item;
    nextInLine([],5);
    return item;
    nextInLine([],1);
    return item;
    nextInLine([2],1);
    return item;
    nextInLine([5,6,7,8,9],1);
    return item;
    nextInLine(testArr, 10);
    return item;
  // 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));

@mikemcmullon

    nextInLine([],5);
    return item;
    nextInLine([],1);
    return item;
    nextInLine([2],1);
    return item;
    nextInLine([5,6,7,8,9],1);
    return item;
    nextInLine(testArr, 10);
    return item;

You should not be calling the function inside of the function here.

@mikemcmullon

  arr.push(6);
  arr.shift();
   return item;

Lets look here. Why are you pushing 6?

What are you doing with the result from shift?

Thanks, that was the focus I needed. It works now.
