So, whether you’re going recursive in Ocaml or going the lazy way in Haskell, you’ll be looping like a pro and writing code that’s both smart and smooth! 

Immutability

In the enchanting world of functional programming, immutability is a sacred principle embraced by both Ocaml and Haskell.  It’s like a magical spell that ensures your data remains unchanged once it’s created.

In Ocaml, the story gets a little twist!  It’s all about balance – while immutability is the norm, there are certain situations where mutable state is allowed. It’s like a magical exception that grants you a bit of flexibility when needed.

But in Haskell, it’s immutability all the way!  Once you create something, it stays unchanged forever. It’s like a sacred vow to keep things pure and unaltered.

So, whether you choose the balanced approach of Ocaml or the strict path of Haskell, one thing’s for sure – immutability is the secret sauce that keeps your code reliable and rock-solid! 

Lazy Evaluation

When it comes to evaluation strategies, Haskell and Ocaml have their own unique approaches! 

In the mesmerizing land of Haskell, it’s all about taking it easy with lazy evaluation.  It’s like having a laid-back genie that only springs into action when values are actually needed. This clever trick can save memory and make your code more efficient.

On the other hand, in the world of Ocaml, it’s all about getting things done eagerly and right away!  It’s like having a super enthusiastic helper that computes values immediately without delay.

So, whether you prefer the chill vibes of Haskell’s lazy evaluation or the eager nature of Ocaml, your code will dance to the rhythm of the evaluation strategy you choose!
