Page: Difference between X (or why X instead of X)

[phated]

When shown Grain, many people ask questions like "What's the difference between Grain and OCaml?" or "Why didn't you just compile OCaml to WASM?", etc etc.

I think we could have a page for why Grain exists and how it differs from OCaml/Reason/Rust/Insert-functional-language-here.
