Jazz documentation

Jazz is an experimental, statically typed functional language. Programs are expressions built from immutable values and functions. Algebraic data types and pattern matching describe data and its alternatives; modules define namespace boundaries; capabilities express the operations required by polymorphic code.

Start with the getting-started overview, then use the language guide to understand how Jazz behaves. Use the reference when you need an exact rule.

Choose a path

• Run Jazz: install the toolchain and work through the first program.
• Learn the language: start with functions, then continue to patterns and modules.
• Look up an API: browse the standard-library modules.
• Understand compilation: follow the architecture and pipeline.
• Follow development: check the current status and roadmap.

Jazz is pre-1.0. The project status distinguishes current behavior from partial and planned work.
