In a scenario where a function calculates the total price of items in a cart, how would making this function pure affect its implementation?
- It would introduce side effects
- It would improve testability and predictability
- It would slow down the function execution
- It would require additional dependencies
Making the function pure in this scenario would involve removing external dependencies and ensuring that the function's output depends only on its input. This enhances testability and predictability, making the function easier to reason about and test in isolation. It also helps in avoiding side effects, which is a key characteristic of pure functions.
