Originally, I was going to use D, but its current WASM guideline is buried under a lot of Discord threads, all while people are lazy to touch the wiki. I need to test stuff with WASM (use for scripting in applications, not browsers).

Please NO RUST!!! While I see why functional programming is useful (I even use wasmtime as my WASM engine, which is developed in Rust), but is horribly counterproductive for game development, especially if it’s opt out like in Rust.

EDIT: In the meanwhile, I’ve found AssemblyScript, which seems to be good for my usecase.

    I made this mistake for ages because Haskell is so popular and it’s functional and pure, but it’s not actually a requirement for functional languages to be pure. OCaml isn’t.

    I didn’t say that FP languages have to necessarily be pure, just that FP languages tackle the problem of mutation by arranging programs such that most things are typically pure and side effects typically happen at the periphery (logging is probably the one exception, though). This is true even in FP languages that allow arbitrary side effects in functions, it’s just not enforced by a compiler.

    I agree Rust code has a different feel to OCaml code but that’s because it makes some things easier (e.g. mutation, vectors). You still could write Rust as if it was OCaml (except for the lack of currying), it’s just that nobody does that because it sucks.

    That’s the entire point, though. It’s all about what the language emphasizes and makes easy to do. If it’s unnatural to write a functional program in Rust and no one does it, then it’s not really reasonable to call it a functional language. Writing functional programs is not idiomatic Rust, and that’s okay.
