Monads achieve this by providing their own data type (a particular type for each type of monad), which represents a specific form of computation, along with one procedure to wrap values of any basic type within the monad (yielding a monadic value) and another to compose functions that output monadic values (called monadic functions).

  • Add a reaction :flag-jp: to the message

  • Check a new message in its thread

  • Click ⚡ (Shortcuts) button
