Learn NIM with Real Code Examples

Nim compiles to C, C++, or JavaScript for portability and speed.

It combines imperative, object-oriented, and functional programming paradigms.

Supports metaprogramming and macros for code generation.

Strong static typing with type inference

Procedures and first-class functions

Object-oriented programming with classes and inheritance

Generics and templates for reusable code

Macros and compile-time execution for metaprogramming

Variables and constants

Procedures and functions

Control flow: if, while, for

Types, arrays, sequences, tuples

Modules and imports

src/ - Nim source files

tests/ - unit and integration tests

examples/ - sample projects

docs/ - documentation

nimble file for package configuration

Write source code (.nim files)

Compile using nim c file.nim

Run binary or JavaScript output

Use Nimble for dependencies

Debug and optimize performance

Beginner: simple scripts and CLI tools

Intermediate: OOP, functional patterns, generics

Advanced: metaprogramming, macros, async code

Expert: game engines, compilers, high-performance systems

Research: domain-specific languages and code generation

Faster than Python due to compilation

Simpler syntax than C/C++

Less mature ecosystem than Rust or Go

Better metaprogramming than most mainstream languages

Flexible paradigms compared to single-paradigm languages
