The Modern JavaScript Bootcamp (2019) - Setting up a Third-Party Library

The video tutorial covers setting up event listeners for item removal in a JavaScript application. It explains the need for unique identifiers to manage items effectively and introduces the use of third-party libraries, specifically UUID, to generate these IDs. The tutorial demonstrates how to implement UUID in both notes and todos applications, ensuring each item has a unique ID. It concludes with testing and verifying the unique ID generation process, emphasizing the efficiency and reliability of using third-party libraries.

Why is it important to assign a unique identifier to each item in an application?

• To reduce the size of the application.

• To make the application run faster.

• To make the application look more appealing.

• To ensure each item can be uniquely identified and manipulated.

What is a third-party library in the context of JavaScript?

• A library that is only used for styling purposes.

• A library written by someone else that can be used in your application.

• A library that is used to store data.

• A library that is built into JavaScript.

What does UUID stand for?

• Universal User Identifier

• Universal Unique ID

• Universally Unique Identifier

• Unique Universal Identifier

Which version of the UUID algorithm is used for generating random unique IDs?

• Version 1

• Version 4

• Version 2

• Version 3

What is the purpose of adding a script tag for a third-party library in an HTML file?

• To add comments to the HTML file.

• To include the library's functionality in the application.

• To style the HTML elements.

• To make the HTML file load faster.

How can you verify that the UUID library is working correctly in your application?

• By checking the console for errors.

• By ensuring each new item has a unique ID.

• By checking the CSS styles.

• By looking at the HTML file.

What should you do if the UUID library service is temporarily down?

• Use a backup URL to access the library.

• Wait until the service is back online.

• Write your own UUID generation code.

• Stop using the library altogether.

What is the main advantage of using third-party libraries in JavaScript applications?

• They are only used for testing purposes.

• They make the application look better.

• They solve common problems efficiently without reinventing the wheel.

• They increase the size of the application.

What is the first step in applying the UUID library to a to-do application?

• Change the color of the to-dos.

• Add new to-dos without IDs.

• Remove the library from the notes application.

• Delete all existing to-dos.

What is a key benefit of using unique IDs in applications with shared attributes?

• It makes the application slower.

• It allows for easier tracking and manipulation of data.

• It reduces the need for a database.

• It increases the complexity of the code.
