  5. Separation of Concerns: Encourages the separation of presentation logic (JSP) and business logic (Java classes/servlets).

Syntax Overview:

JSP files typically have the .jsp extension and include special tags:

  • Scriptlets (<% %>): Embed Java code.
  • Expressions (<%= %>): Output the result of a Java expression.
  • Directives (<%@ %>): Provide instructions to the JSP container (e.g., import packages, set page encoding).
  • Declarations (<%! %>): Declare variables or methods.

Advantages

  1. Simplifies the creation of dynamic content.
  2. Platform-independent (runs on any server that supports Java).
  3. Supports MVC (Model-View-Controller) architecture when used with servlets and frameworks.

How JSP works:

  1. A JSP file is deployed on a web server that supports JSP (e.g., Apache Tomcat).

  • Razor Views: ASP.NET Core MVC uses Razor, a templating engine that allows developers to embed C# code directly within HTML for dynamic page rendering.
  • Middleware Pipeline: ASP.NET Core uses middleware components to process requests and responses. This allows you to add functionality such as authentication, logging, etc., to the application.

3. Advantages of ASP.NET Core MVC.

  • Unified Framework: ASP.NET Core MVC unifies the previous MVC and Web API frameworks, allowing developers to build both web pages and APIs using the same framework.
  • ModularityThe framework is designed to be modular, so you can include only the components you need, reducing the overhead.
  • Built-in Security Features: Features like data protection, authentication, and authorization are built-in, making it easier to secure your web application.
  • Support for RESTful APIs: In addition to serving web pages, ASP.NET Core MVC is also commonly used for building RESTful APIs, providing a clean separation between data and UI.

4. Common Uses:

  • Web Applications: Building traditional web applications that have server-rendered pages.
  • REST APIs: Developing APIs that can be consumed by mobile apps, other web services, or client-side JavaScript.
  • Single Page Applications (SPA): While typically used for server-side rendered apps, ASP.NET Core MVC can also work well with front-end JavaScript frameworks like Angular, React, or Vue.js for building SPAs.
