## Description

Popmotion is a JavaScript animation library and declarative motion engine designed for creating programmatic motion and interactive transitions within web user interfaces. It provides a functional animation API that allows developers to define complex animation sequences through configuration objects rather than manual frame management.

The engine utilizes a functional approach to animate user interface elements, implementing spring-based physics simulations to mimic real-world momentum. It employs interpolation-based value mapping and functional transformations to translate animation progress into specific visual movements.

The library covers a broad range of web frontend visual effects, including interactive element feedback and fluid user interface transitions. Its architecture decouples the calculation of animated values from the render target, synchronizing updates with the browser's native refresh cycle.
