### What are the benefits associated with using pure functions?On an educational website, this text can be introduced in a section dedicated to functional programming or software development best practices. Below are some key benefits associated with using pure functions, which you might find on such a website:1. **Predictability**: Pure functions always produce the same output given the same input, making their behavior predictable and easier to understand. 2. **Testability**: Because pure functions do not depend on or affect the program's state, they are easier to test. You just need to provide the input and check the output. 3. **Concurrency**: Pure functions do not interact with shared states, which minimizes the risk of bugs caused by concurrent processes since there are no side effects. 4. **Debugging and Maintenance**: Reduced side effects mean fewer unexpected interactions between different parts of the program, making it easier to debug and maintain. 5. **Memoization**: Since pure functions always generate the same output for the same input, caching the results of expensive function calls can improve performance through memoization. 6. **Refactoring**: Pure functions make refactoring code easier as their independent nature minimizes the risk of affecting other parts of the program.Graphs or diagrams might include:- **Diagram**: A flow chart illustrating the input-output relationship of pure functions.- **Graph**: A comparison graph showing reduced debugging time or improved test coverage when using pure versus impure functions. In the absence of any visual aids in the provided image, these textual explanations and suggested visual aids should effectively convey the benefits of pure functions.

4. **Debugging and Maintenance**: Reduced side effects mean fewer unexpected interactions between different parts of the program, making it easier to debug and maintain.

5. **Memoization**: Since pure functions always generate the same output for the same input, caching the results of expensive function calls can improve performance through memoization.

6. **Refactoring**: Pure functions make refactoring code easier as their independent nature minimizes the risk of affecting other parts of the program.
