EDIT: Thanks to someone's response, I got a portion working. It now adds topping prices no problem. However, it adds a price even when a user doesn't put toppings into the prompt. I've updated my code below.

EDIT 2: For full code, here's my github link. It's updated with the below code (and the rest of the coding) https://github.com/cas389/m4-hw6-ju-cheryl.

I'm in a JavaScript class, and I am stuck on this portion of my homework assignment. Basically, we are creating a pizza ordering system where a user would fill out if they want thin/thick/pan crust, which toppings they want, if they want extra cheese and finally if they want delivery.

I have everything except the pizza toppings part. This is the information for this section (including the comments the teacher gave us as "hints") along with what I've been trying to make work. I've cut out all the sections I've already finished.

function getPizzaOrder() {
  var extraCheeseUpcharge = 1.5
  var thickCrustUpcharge = 2
  var deliveryFee = 3.5
  var toppingsFee = 1.5
  var basePrice = 10

  var toppings = prompt("Please enter additional toppings (comma separated)")
      // HINT: prompt() will return an empty string "" if the user presses 'OK' without entering a value
      // if the user enters toppings, use .split(",") to separate toppings into an array
      // if no toppings are given, make sure pizza.toppings is set to []
      // if the user has added toppings, add toppingsFee multiplied by
      // the number of toppings added to pizza.cost
      // YOUR CODE HERE
    
       pizza.toppings = [];
       pizza.toppings = toppings.split(',');
       for (let i = 0; i < pizza.toppings.length; i++){
           pizza.cost += toppingsFee;
       }
       console.log(pizza.toppings);




  return pizza
}
