Custom HTTP Library (Fetch with Async Await) - Part 4

The video tutorial demonstrates how to refactor JavaScript code to use async/await instead of promises for handling HTTP requests. It covers renaming a project to easy HTTP 3, updating JavaScript files, and implementing GET, POST, PUT, and DELETE methods using async/await. The tutorial concludes with a comparison of async/await and promises, offering different options for handling asynchronous operations.

What is the main purpose of transitioning from promises to async/await in the tutorial?

• To remove the need for error handling

• To make the code more complex

• To improve code readability and maintainability

• To increase the execution time

In the refactored GET request, what is the role of the 'await' keyword?

• It converts the function into a promise

• It speeds up the function execution

• It automatically handles errors

• It pauses the function execution until the promise is resolved

What is the outcome of the POST request implementation in the tutorial?

• A new user is added with an ID of 11

• The server crashes

• The existing user data is deleted

• The user data is not modified

How does the async/await approach affect the PUT request in the tutorial?

• It makes the PUT request slower

• It makes the PUT request asynchronous

• It simplifies the code by removing the need for explicit promise handling

• It requires more lines of code

What is the benefit of using async/await for the DELETE request as shown in the tutorial?

• It automatically retries the request on failure

• It eliminates the need for a return statement

• It provides a cleaner and more readable code structure

• It allows for synchronous execution

What does the tutorial suggest about using async/await versus promises?

• Async/await is only for server-side code

• Promises are always better than async/await

• Async/await is mandatory for all JavaScript projects

• The choice between async/await and promises is a matter of preference

What is the final outcome of the DELETE request in the tutorial?

• The resource is updated

• The resource is deleted

• The resource is duplicated

• The resource remains unchanged
