JavaScript Masterclass - Zero to Job-Ready with Hands-On Projects - Fetch News Data / 245

The video tutorial covers how to send fetch requests in JavaScript, handle responses using async await, and manage errors with try-catch. It demonstrates processing API data, creating dynamic HTML cards, and formatting data for display. The tutorial concludes with a review and outlines future steps for categorizing requests.

Why is it important to use your own API key when making fetch requests?

• To ensure you have unlimited requests

• To avoid using up someone else's request limit

• To prevent errors in the code

• To make the code run faster

What is the purpose of using async/await in JavaScript?

• To simplify the handling of asynchronous operations

• To increase the speed of the code execution

• To handle errors more effectively

• To make the code run synchronously

Why is it necessary to handle errors using try-catch in asynchronous functions?

• To prevent the code from running

• To ensure the code runs faster

• To handle potential issues like API key errors or server downtime

• To make the code more readable

What does the .then method do when handling promises?

• It catches errors in the promise

• It cancels the promise

• It logs the promise to the console

• It allows access to the resolved value of the promise

What is the result of calling a fetch request without handling the promise?

• The request will fail

• The request will return undefined

• The request will return a promise object

• The request will automatically resolve

How can you access individual articles from the fetched data?

• By using the .forEach method

• By using the .filter method

• By using the .map method

• By using a for loop

What is the purpose of dynamically creating HTML cards?

• To reduce the amount of JavaScript code

• To make the webpage responsive

• To display fetched data in a structured format

• To improve the performance of the webpage

What method is used to format the time from the fetched data?

• Using the Date object

• Using string methods like replace and split

• Using a third-party library

• Using a regular expression

How can you ensure that only fetched news is displayed on the page?

• By using a different API

• By setting a timeout

• By using a filter function

• By removing default cards from the HTML

What is the benefit of using a template for creating HTML cards?

• It makes the code run faster

• It allows for consistent styling and structure

• It reduces the number of API requests

• It simplifies the JavaScript code
