Explain the reason as to why express ‘app’ and ‘server’ must be kept separate.

Answer Posted / Jitendra Kumar Mishra

In Node.js with Express, it is essential to keep the application (app) and server separate for better organization, modularity, and testability:n
1. Organization: Keeping app and server separate makes the code more readable and easier to understand, as each file has a specific purpose.n
2. Modularity: By separating the app from the server, you can create reusable modules that can be used in other projects or applications.n
3. Testability: Separating the app from the server allows for more effective testing, as you can easily test your application logic without having to worry about the server configuration.
