# Haskell Cheat
Fun only to see how a pure functional language is like.
Official tutorial list:
-
Good O'Reilly published tutorial.
## Type inference
Haskell compiles, but infers the type of any expression.
This allows you not to write huge namespaced types like in C++.
This is somewhat the path that C++ is just now starting to take with features like `auto`.
## Pure
Haskell strongly encourages you to separate pure from impure code.
Pure code cannot have state. E.g., the output of a function can depend only on it's input, and the function cannot have side effects like writing to a file or setting a global variable.
This says a lot about the function. For example, if you know that a function has signature:
Bool -> Bool
Then there are only 4 possible functions:
- True constant
- False constant
- negator
- identity
In a language like C, this is of course not possible since the output of the function can depend on global variables.
