inCart computed property should be used (L10)

[lazarosmitsis]

I think a new computed property should be used to disable/enable the "Remove Item" button.
Instead of checking inStock property, a new inCart property should be used.
The "Remove Item" button should be enabled only if the product id exists in cart - not if it exists in stock!

This is the solution proposed by L10-end:

    <button 
    class="button" 
    :class="{ disabledButton: !inStock }" 
    :disabled="!inStock" 
    @click="removeFromCart">
    Remove Item
  </button>
  <!-- solution -->

This is what I would suggest:

    <button 
    class="button" 
    :class="{ disabledButton: !inCart }" 
    :disabled="!inCart" 
    @click="removeFromCart">
    Remove Item
  </button>
  <!-- solution -->
