Browser API's: The unknown super heroes
summary
Demos prove concrete outcomes: Geolocation API returns latitude/longitude and plots it on Google Maps; Battery Status API reports 48% and ~6400s drain enabling adaptive asset loading; Memory API exposes device RAM (capped at 8GB); audio demo records via mediaDevices into Blobs, generates oscillators up to ultrasonic tones, and drives a synth over the Web MIDI API to play “Twinkle Twinkle”; camera frames stream to canvas for filters, page visibility pauses video, vibration works on Android, and the Web Bluetooth API connects and moves a toy robot (brief disconnects observed).
