SwiftUI and Node.js Full Stack - Build Twitter - iOS 16 - Create User

In this tutorial, we learn how to create a router for user creation using Express in JavaScript. The process involves setting up a new folder for routers, requiring necessary modules, and defining a POST endpoint. We handle asynchronous operations using async/await and try-catch blocks to save users to a database. The router is then integrated into the main app, and the endpoint is tested using Postman. Despite encountering some errors, the tutorial provides a comprehensive guide to setting up a user creation endpoint.

Explain the importance of using 'try and catch' in asynchronous functions.

What is the expected response when a user is successfully created?

What steps are necessary to connect the user router to the index.js file?

How do you test the user creation endpoint using Postman?
