Full Stack Web Development MASTERY Course - Novice to Expert - Building REST API with Asynchronous Function

The video tutorial covers creating a RESTful API and saving data in MongoDB using the POST method. It explains the concept of promises and introduces async/await functions to handle asynchronous operations more efficiently. The tutorial demonstrates how to replace promises with async/await in API operations, focusing on error handling using try/catch blocks. The implementation is tested using Postman and MongoDB Compass, showcasing the optimized API's functionality.

What is the primary purpose of using the POST method in a RESTful API?

• To update existing data on the server

• To retrieve data from the server

• To add new data to the server

• To delete data from the server

In the context of the video, what does the 'save' method do?

• It deletes data from the database

• It retrieves data from the database

• It saves new data to the database

• It updates existing data in the database

Why is it beneficial to use async/await functions in handling promises?

• They automatically resolve all promises

• They allow other tasks to execute without waiting

• They eliminate the need for error handling

• They make the code run synchronously

What is the role of the try-catch block in async/await functions?

• To handle errors that occur during asynchronous operations

• To automatically retry failed promises

• To execute code only if a promise is resolved

• To convert synchronous code into asynchronous code

Which status code is typically used to indicate a successful POST operation?

• 400

• 201

• 404

• 200

What tool is used to verify data storage in MongoDB during the demonstration?

• Postman

• Node.js

• Express.js

• MongoDB Compass

What is the main advantage of optimizing APIs with async/await?

• It reduces the code size significantly

• It improves the readability of the code

• It enhances the performance by handling asynchronous tasks efficiently

• It eliminates the need for a database
