title: Create a shopping list using Javascript
body: <p>Hello so I am trying to work on this code for my Java Script class and I am stuck on how to proceed. The instructions for the problem we were given were as follows:</p>
  
  <p>Create a simple self-checkout system. Prompt for the prices and quantities of three items. Calculate the subtotal of the items. Then calculate the tax using a tax rate of 5%. Print out the line items with the quantity and total, and then print out the subtotal, tax amount, and total. </p>
  
  <p>Here is my code so far:</p>
  
  <pre><code>// Make a function for a simple self-checkout system. 
  // prompt the user for quantity of the items
  // Prompt the user for the prices of the items
  
  function self_Checkout () {
  
  
    var prices = [x, y, z,];
    var x = prompt('Enter value');
    var quantity_x = prompt('Enter value for quantity of item 1');
    return x * quantity_x;}
  { if 
    var y = prompt('Enter value');
    var quantity_y = prompt('Enter value for quantity of item 2');
    return y * quantity_y;
  { if
    var z = prompt('Enter value');
    var quantity_z = prompt('Enter value for quantity of item 3');
    return z * quantity_y;
  
  
    // Multiply entire total by a tax rate of 5%
    // Return value of total of all items + tax to user 
    // Use console.log or document.write?
  </code></pre>
  
  <p>}</p>
  
  <p>Now the assignment also mentions how we are supposed to use loops objects and arrays also in this problem. I have attempted to add a array in the code. Some help on how to proceed in my code would be much appreciated, hopefully i explained it well enough to get some help. </p>
