Performance Features
- Hardware acceleration on iOS (and other modern browsers) makes it feel as smooth as native apps
- Utilizing CSS3 features like Transitions, Transforms, requestAnimationFrame where possible to make panning and zooming really smooth
- Smart polyline/polygon rendering with dynamic clipping and simplification makes it responsive even when displaying objects with thousands of points
- Modular design and a build system allow you to reduce the library size by leaving out features you don't need
- Tap delay elimination on mobile devices makes controls and layers respond to taps immediately
