Question 3

+3 marksOne correct option

Consider the following Vue.js application with two different route scenarios and a component that uses reactive data binding:
Scenario: An e-commerce application where: Product list component displays products filtered by category• Category changes through router parameters: /products/:category• When a user navigates from /products/electronics to /products/books, the product list should update • Component Code:

If the developer changed the template to use displayedProducts instead of filteredProducts, What would be the most likely issue?

  1. A

    Performance would improve because computed properties are slower than data

  2. B

    The initial page load would show an empty list, and only after navigation would data appear correctly

  3. C

    There would be no difference because both will update at the same time

  4. D

    The application would crash because displayedProducts is reactive
