Summary

Janet is a fast, dynamic programming language built around a core library of 600 functions and macros. It offers a minimal setup with a single binary and supports features like threads, networking, event loops, garbage collection, closures, green threads, continuations, and immutable/mutable data structures. Key aspects include direct C interoperability, macro support, tail call optimization, and a REPL with debugging capabilities. Janet allows for exporting projects to standalone executables using a companion build tool (jpm), and integrating with Erlang-style supervision trees. The language utilizes Parsing Expression Grammars and lexical scoping. It also provides options for various usage scenarios, including debugging, REPL interaction, and compiling/loading images or source code.
