Functional functions- map // "for each"- tee // fork- reduce // array to scalar- etc...

Functions that take outside parameters and return composable functions.

URN

1. Find/discover/identify door camera2. Create workflow:

a. Take snapshot(s) using camera API (or accept as event)b. Upload snapshot(s) to Google Vision APIc. Retrieve results JSON: [

"weapon", "gun", "person", "male", etc...]

d. Condition: if not person && weapon { exit}

e. Use API to text $number3. Register event (webhook, cron job, etc).
