A Snapshot of the Mobile HTML5 Revolution
4 likes2,545 views
The document discusses the evolution of HTML5 and mobile applications. It notes that HTML5 allows building applications that work across different devices using a single codebase, but that native apps still have advantages in terms of performance and access to device functionality. Hybrid apps use a native wrapper and WebView to bridge this gap by allowing HTML5 apps to access device APIs while retaining cross-platform capabilities. Overall the document examines the tradeoffs between different mobile app approaches.
