Erlang vs ReasonML: What are the differences?

<Write Introduction here>

1. **Concurrency Model**: Erlang uses the actor model while ReasonML uses the React-based models. In Erlang, each "process" acts like a separate entity with its own memory, while in ReasonML, components in React manage their own state.
2. **Typing System**: Erlang is dynamically typed, meaning type checking is done at runtime, whereas ReasonML is statically typed with strong type inference, catching errors at compile time.
3. **Language Paradigm**: Erlang follows a functional programming paradigm, where functions are first-class citizens and immutable data structures are favored, while ReasonML combines functional and imperative programming with its syntax resembling OCaml.
4. **Tooling Support**: Erlang has its own OTP framework for building scalable and fault-tolerant systems, whereas ReasonML benefits from the vast tooling support of JavaScript ecosystem due to its compatibility with it.
5. **Compilation Targets**: Erlang code is compiled into bytecode that runs on the Erlang Virtual Machine (BEAM), whereas ReasonML code is compiled into JavaScript, enabling it to be used for front-end development.
6. **Community Support**: Erlang has a strong community focusing on telecom applications and distributed systems, while ReasonML community, being relatively newer, is more diverse with a focus on web development and tooling.

In Summary, Erlang and ReasonML differ in their concurrency model, typing system, language paradigm, tooling support, compilation targets, and community focus.
