Characteristic	CoffeeScript	Grain
Syntax	Concise, Python-inspired syntax that compiles to JavaScript; significant whitespace and minimal punctuation.	Functional, ML-inspired syntax with type inference; similar to OCaml or ReasonML.
Paradigm	Multi-paradigm, but primarily imperative and object-oriented, mirroring JavaScript.	Purely functional, emphasizing immutability and functional programming concepts.
Typing	Dynamically typed, inherits JavaScript's type system.	Statically typed with strong type inference.
Performance	Performance is similar to JavaScript since it compiles directly to it.	Compiles to WebAssembly, offering potentially better performance for compute-heavy tasks in the browser.
Libraries and frameworks	Can use any JavaScript library or framework.	Limited ecosystem; can interoperate with JavaScript/WebAssembly, but fewer native libraries.
Community and support	Mature but declining community; less active development and support.	Small, growing community; active development but limited resources and support.
Learning curve	Low for those familiar with JavaScript; easy to pick up.	Moderate to steep, especially for those new to functional programming or ML-family languages.
