ComponentKit uses a declarative API to define UI components. You simply describe the layout for your UI based on a set of immutable inputs and the framework takes care of the rest. With code generation, ComponentKit can perform optimizations for your UI under the hood, while keeping your code simple and easy to maintain.
ComponentKit can measure and layout your UI ahead of time without blocking the UI thread. By decoupling its layout system from UIKit, ComponentKit can drop the UI thread constraint.
Flatter View Hierarchies
ComponentKit uses Yoga for layout and automatically reduces the number of UIViews that your UI contains. This, in addition to ComponentKit's text optimizations, allows for much smaller view hierarchies and improves both memory and scroll performance.
With ComponentKit, each UI item such as text, image, or video is recycled individually. As soon as an item goes off screen, it can be reused anywhere in the UI and pieced together with other items to create new UI elements. Such recycling reduces the need of having multiple view types and improves memory usage and scroll performance.
