+Janet is a functional and imperative programming language and bytecode
+interpreter. It is a modern lisp, but lists are replaced by other data
+structures with better utility and performance (arrays, tables, structs,
+tuples). The language also supports bridging to native code written in
+C, meta-programming with macros, and bytecode assembly.
