2. Frameworks in Programming

Frameworks are pre-written sets of code that developers can use to build applications more quickly. They provide structure and reusable components, allowing programmers to focus on the unique aspects of their applications instead of reinventing the wheel. Frameworks often come with libraries, tools, and best practices built-in.

a. What is a Framework?

A framework provides a foundation for developers to build applications without having to start from scratch. Frameworks follow a specific set of conventions and architecture, which ensures consistency and efficiency in development.

For example, rather than manually handling tasks like routing, data handling, and user authentication, a framework would provide built-in functions for these tasks.

b. Popular Frameworks by Category
