Here's our take.

Applicative Functor

Nice Pick

Developers should learn applicative functors when working in functional languages like Haskell, Scala, or F# to handle computations with effects (e

Pros

• g
• Related to: functional-programming, functors

Cons

• Specific tradeoffs depend on your use case

Arrow Functors

Developers should learn arrow functors when working in functional programming environments, especially in Haskell or Scala, to handle side effects, manage state, or implement domain-specific languages (DSLs) with enhanced composability

Pros

• They are valuable for tasks like parsing, GUI programming, or reactive systems where computations need to be combined in flexible, law-abiding ways, offering an alternative to monads when more structure or parallelism is required
• Related to: haskell, functional-programming

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Applicative Functor if: You want g and can live with specific tradeoffs depend on your use case.

Use Arrow Functors if: You prioritize they are valuable for tasks like parsing, gui programming, or reactive systems where computations need to be combined in flexible, law-abiding ways, offering an alternative to monads when more structure or parallelism is required over what Applicative Functor offers.

The Bottom Line

Applicative Functor wins

Developers should learn applicative functors when working in functional languages like Haskell, Scala, or F# to handle computations with effects (e
