Nim

Nim is a statically typed, compiled systems programming language that combines the speed of C, the expressiveness of Python, and the type safety of Rust. Created by Andreas Rumpf in 2008, Nim has over 16,000 stars as of 2026 and is designed to be efficient, expressive, and elegant. Nim compiles to C, C++, Objective-C, or JavaScript, enabling deployment on virtually any platform with native performance. Key features include: Python-like indentation-based syntax (making it easy to read and write, with a gentle learning curve for Python developers), static typing with type inference (reducing boilerplate while maintaining compile-time safety), garbage collection options (multiple GC algorithms including ARC and ORC for deterministic memory management, plus manual memory management for real-time systems), metaprogramming via macros and templates (an AST-based macro system more powerful than C preprocessor macros, enabling compile-time code generation, DSL creation, and compile-time function execution), compile-time function execution (FTC, running arbitrary Nim code during compilation), C, C++, and JavaScript compilation targets (enabling native binaries, WebAssembly via JavaScript target, and cross-compilation to embedded systems), interoperability with C and C++ (calling C libraries directly with no FFI overhead via importc pragma), generics and type classes (parametric polymorphism with constraints), async/await support for asynchronous programming, effect system (tracking side effects like IO, GC, and exceptions at compile time), exception handling, object-oriented programming (methods, inheritance, and multiple dispatch), and a growing ecosystem of packages via Nimble package manager.
