Haskell vs OCaml: What are the differences?
Developers describe Haskell as "An advanced purely-functional programming language". . On the other hand, OCaml is detailed as "A general purpose industrial-strength programming language". It is an industrial strength programming language supporting functional, imperative and object-oriented styles. It is the technology of choice in companies where a single mistake can cost millions and speed matters, .
Haskell and OCaml can be categorized as "Languages" tools.
thoughtbot, Wagon, and CentralApp are some of the popular companies that use Haskell, whereas OCaml is used by Hammer Lab, NG Informática, and Maersk Digital. Haskell has a broader approval, being mentioned in 47 company stacks & 337 developers stacks; compared to OCaml, which is listed in 6 company stacks and 6 developer stacks.
