What are pure functions and how are they used in real-world applications?
Pure functions are functions that always produce the same output for the same input and have no side effects. They are widely used in functional programming and can simplify debugging and testing.
Can you give me an example of a pure function?
Sure! A simple example of a pure function is a function that adds two numbers together. For instance, add(a, b) { return a + b; }
always returns the same result for the same inputs.
How do pure functions help in software development?
Pure functions enhance code maintainability, make it easier to reason about the code, and facilitate parallel execution since they don't rely on shared state.
Are there any drawbacks to using pure functions?
One drawback is that pure functions can sometimes lead to more complex code when dealing with stateful operations, as you may need to manage state externally.
