This means that writing pure functions in Haskell requires much less discipline (if any) than doing so in C#. In Haskell, functions are pure by default and values are immutable by default. The Haskell programming language has a different story altogether. This is true because in C#, it is easy to mutate a parameter, get or set the value of a static field, read from or write to a file, etc. In the same article, the author also mentions that in C#, developers are required to have some discipline to write pure code. Also, a pure function cannot call another function that is impure. Also, a pure function has no side effects.Īll of this means that a pure function cannot mutate a parameter, mutate or read global state, read a file, write to a file, etc.

If we invoke a pure function twice using the same input values, we are guaranteed to get the same output.
