Stencil is a compiler that generates Web Components (more specifically, Custom Elements). Stencil combines the best concepts of the most popular frameworks into a simple build-time tool.
Stencil takes features such as
- Virtual DOM
- Async rendering (inspired by React Fiber)
- Reactive data-binding
and then generates standards-based Web Components with these features baked in.
Stencil will be used in Ionic 4, making its component usable within Vue or React.
