What are the laws of monads in functional programming?
The laws of monads are essential for ensuring that monads behave consistently. They include the left identity, right identity, and associativity laws.
Can you explain the left identity law?
Sure! The left identity law states that if you take a value and wrap it in a monad, then bind it to a function, it should be the same as just applying the function to the value.
What about the right identity law?
The right identity law states that if you have a monadic value and you bind it to the 'return' function of the monad, it should return the original monadic value unchanged.
And what does associativity mean in this context?
Associativity means that when you have multiple binds, the order in which you apply them shouldn't matter. The result will be the same regardless of how you group the operations.
