Modern JavaScript from the Beginning - Second Edition - Delete Ideas

The video tutorial covers the implementation of delete functionality for ideas in a full-stack application. It begins by explaining the conditions under which ideas can be deleted, followed by the implementation of update and delete methods using axios. The tutorial then details setting up event listeners for deletion and handling the logic to delete ideas from both the server and the DOM. Finally, it discusses conditional rendering of the delete button based on the user's username stored in local storage.

What condition must be met for the delete button to be visible?

• The user must be logged in with any username.

• The user must have the username stored in local storage.

• The user must be an admin.

• The user must have a premium account.

What HTTP method is used to update an idea in the Ideas API service?

• GET

• POST

• PUT

• DELETE

Why is the username included in the delete request?

• To verify the user's identity.

• To send a notification to the user.

• To log the deletion action.

• To ensure the username matches the idea's owner.

What is the purpose of event delegation in setting up the delete button?

• To improve performance by reducing the number of event listeners.

• To ensure the event listener is only attached to the delete button.

• To allow multiple buttons to be clicked simultaneously.

• To prevent the event from being triggered.

How is the idea ID retrieved in the event listener?

• By querying the database directly.

• By using a global variable.

• By accessing a custom data attribute.

• By reading the URL.

What happens if the username does not match when trying to delete an idea?

• The idea is deleted anyway.

• An error message is displayed.

• The page is refreshed.

• The user is logged out.

What is the purpose of filtering the ideas array during deletion?

• To duplicate the idea.

• To sort the ideas alphabetically.

• To remove the idea from the array.

• To add a new idea.

How is the delete button conditionally rendered?

• By checking the idea's creation date.

• By verifying the user's email.

• By comparing the idea's username with the stored username.

• By checking the user's role.

What technology is used for the front end of the application?

• Vue.js

• Vanilla JavaScript

• Angular

• React

What is suggested for further learning after completing the application?

• To add more features to the application.

• To focus on backend development only.

• To start a new project from scratch.

• To learn a new programming language.
