One of the most unusual parts of MatchBox is the ESP32 target.

The MatchBox open beta is available at https://github.com/ortus-boxlang/matchbox, and it can compile BoxLang scripts into bytecode and deploy them to ESP32 microcontrollers. That means the same language used for scripts, native tools, web services, and browser logic can also run on a small embedded device.

Every production application carries secrets: database passwords, API tokens, encryption keys. The question is never whether to manage them -- it's how badly the current approach is going to hurt you.

In Part 1, we covered BoxLang's first-class range system: lazy evaluation, exclusive boundaries, built-in types (integers, decimals, characters, dates), custom stepping, Java Stream integration, and contains() semantics. If you haven't read it yet, start there.
