HTML5 JavaScript APIs
summary
Claims that the JavaScript APIs are the big part of HTML5 and even bets a 2022 date for interoperable browser support; demos show web forms validation reducing custom JS, a one‑line <video> with play/pause controls and a video on canvas mirror and pixel‑swap effect, a Rubik’s‑cube app using the application cache manifest for offline use, web workers moving prime‑number crunching off the main thread. Notes which browsers actually implement features (Safari/Opera/Firefox variances), codec and cache bugs, and that WebSQL is effectively Safari‑only.
