efficient, expressive, elegant

Nim generates native dependency-free executables, not dependent on a virtual machine, which are small and allow easy redistribution.

The Nim compiler and the generated executables support all major platforms like Windows, Linux, BSD and macOS.

Nim's memory management is deterministic and customizable with destructors and move semantics, inspired by C++ and Rust.

It is well-suited for embedded, hard-realtime systems. Modern concepts like zero-overhead iterators and compile-time evaluation of user-defined functions, in combination with the preference of value-based datatypes allocated on the stack, lead to extremely performant code.

Support for various backends: it compiles to C, C++ or JavaScript so that Nim can be used for all backend and frontend needs.

Nim is self-contained: the compiler and the standard library are implemented in Nim.

Nim has a powerful macro system which allows direct manipulation of the AST, offering nearly unlimited opportunities.

Macros cannot change Nim's syntax because there is no need for it — the syntax is flexible enough.

Modern type system with local type inference, tuples, generics and sum types.

Statements are grouped by indentation but can span multiple lines.
