3. Can you explain the difference between a framework and a library in terms of software development?

A framework and a library are both tools used for software development. However, there are some key differences between them in terms of their functionality and purpose.

1. Definition:
– A library is a collection of code that can be called by the user to perform specific tasks or operations. It consists of pre-written reusable code that can be used in different projects.
– On the other hand, a framework provides a structure and set of rules that dictate how your application should be designed, organized, and executed. It also includes libraries but has additional features, such as predefined architectures and design patterns.

2. Inversion of Control:
– Libraries follow the “Inversion of Control” principle where the flow of control is within the user’s hands. The user calls specific functions from a library when needed to perform a task.
– Frameworks, on the other hand, follow the “Hollywood Principle,” which states “don’t call us; we’ll call you.” This means that the control over the flow is with the framework itself. The user needs to fit their code into the framework’s structure and let it handle execution.

3. Extensibility:
– Libraries have limited extensibility as they only provide specific functionalities for which they were created.
– Frameworks, on the other hand, are more extensible as they provide a foundation for developing custom applications by allowing users to add their own code to extend its functionality.

4. Code ownership:
– Libraries do not impose any coding standards or restrictions on the user’s code.
– Frameworks have strict rules and guidelines that need to be followed while coding. This makes it easier for developers to understand each other’s code as they all follow a standard structure.

5.Coding approach:
– With libraries, developers can pick and choose only those modules or functions they need in their application at any given time.
– With frameworks, developers need to build their entire application around its architecture, which means that they may have to build some features from scratch even if they are already available in a library.

In summary, while both frameworks and libraries provide code that can be reused, their main difference lies in their approach. Libraries focus on providing individual functions or tools, while frameworks provide a complete structure for developing an application.

4. What are some popular programming languages that have their own frameworks or libraries?
