Nim

Nim v2.0 (2023/2024) made ORC (Deterministic Memory Management) the default. It compiles to C/C++/JS and offers Python-like syntax with C-like speeds.

When to Use

Game Development: Hot reloading and performance.
Embedded: Compiles to small C code requiring no runtime.
Scripting: Compiles so fast it feels like a script (
```
nim r
```
).

Core Concepts

Metaprogramming

First-class support. You can rewrite the AST to create DSLs.

ORC

Cycle-collecting ARC. Automatic memory management without pauses.

Backends

Can compile to C, C++, Objective-C, or JavaScript.

Best Practices (2025)

Do:

Use
ARC/ORC
: The default in v2.0. Clean up is deterministic (destructors).
Use
f-strings
:
```
fmt"Hello {name}"
```
.
Use
karax
: For frontend (compiling Nim to JS).

Don't:

Don't mix styles: Choose PascalCase or camelCase (Nim is style-insensitive but consistency matters).
