A Fast, Open Source JavaScript, Canvas & Audio Implementation for iOS
...Developers place their JavaScript canvas app inside the Xcode project, include an index.js file, and build it as a native Apple platform application. It uses Apple platform technologies such as JavaScriptCore and provides a bridge for graphics and audio behavior. While it is an older project, it remains useful as a reference for lightweight JavaScript runtimes built around canvas-first app delivery.
