- While they can be both used for programming all kind of software and even look a bit similar, they are totally different in core functionality. Speaking of static typing vs dynamic typing, no one would want to switch to a dynamic typed language after experiencing Haskell. Guest • Aug 2015 • 7 agrees and 2 disagrees

- Java does not support tail call optimization-- an extremely important FP feature. Java didn't even have lambdas until recently. Java does not run natively like Haskell. Java almost requires OOP whereas Haskell is functional. Java's type system is very different (even inferior) from Haskell's. Guest • Jun 2020 • 2 agrees and 0 disagrees

C (programming language)

C is a general-purpose computer programming language. C is one of the most widely used programming languages of all time.
- C does not guarantee type safety, does not guarantee immutability nor thread safety, does not have functional quality of life improvements like list comprehensions etc. Guest • Jun 2020 • 1 agrees and 0 disagrees

Rust

A systems programming language that runs blazingly fast, prevents almost all crashes, and eliminates data races. .
- Data in Rust is immutable by default which matches Haskell's behavior. Rust's type system is similar to Haskell's. Rust support tail call optimization. Rust's option type supports basically the same error handling paradigm as Haskell's Maybe. Rust does not really use classes, but rather supports the definition of a data type and functions/methods that operate on that data type. Rust and Haskell both support pattern matching. Rust and Haskell both compile to native. Guest • Jun 2020
