What are pure functions?

Can you explain what pure functions are in programming?

Sure! Pure functions are functions that always produce the same output for the same input and do not have side effects.

What do you mean by side effects?

Side effects are changes that a function makes outside its own scope, like modifying a global variable or changing an input parameter.

Can you give me an example of a pure function?

Absolutely! A simple example is a function that adds two numbers together. It always returns the same result for the same inputs.

Why are pure functions important?

They are important because they make code easier to understand, test, and debug, leading to more reliable software.
