Nim vs OCaml: What are the differences?

Introduction:
Below are the key differences between Nim and OCaml explained in detail:

1. **Programming Paradigm**: Nim is a multi-paradigm language that supports imperative, procedural, and object-oriented programming, while OCaml is primarily a functional programming language with support for imperative and object-oriented features.
2. **Type System**: Nim has a more flexible and dynamic type system with type inference, allowing for easier coding and less boilerplate, whereas OCaml has a strong static type system that ensures type safety and prevents many common programming errors.
3. **Performance**: Nim has better performance due to its efficient compilation to native code, making it suitable for systems programming and low-level tasks, while OCaml's performance is good for a high-level language but not as competitive as Nim for low-level tasks.
4. **Community and Ecosystem**: OCaml has a larger and more established community with a rich ecosystem of libraries and tools, which can be beneficial for beginners and developers looking for comprehensive support, unlike Nim, which has a smaller community and ecosystem but is growing steadily.
5. **Syntax and Readability**: Nim has a more familiar and readable syntax similar to Python, making it easier to learn and use for programmers coming from other languages, whereas OCaml's syntax, inspired by ML, might be more challenging for beginners but offers powerful pattern matching and functional programming constructs.
6. **Tooling and Development Environment**: Nim offers a simpler build system and a comprehensive standard library, making it easier to set up and start coding, while OCaml's tooling like OPAM package manager and Merlin IDE integration provides robust support for larger projects and collaborations.

In Summary, key differences between Nim and OCaml encompass programming paradigms, type systems, performance, community size, syntax readability, and tooling/development environments.
