React CountUp

react-countup is a React component that provides an easy-to-use wrapper around the CountUp.js library, enabling numerical value animations within React applications. As of version 6.5.3, the library is actively maintained, with frequent patch and minor releases primarily focused on dependency updates, bug fixes, and incorporating new features from the underlying countup.js library, such as `useIndianSeparators` and scroll spy enhancements. It offers both a declarative component API (<CountUp />), a flexible render prop pattern, and a `useCountUp` hook for more fine-grained imperative control over the animation instance. Key differentiators include its robust API for controlling animation duration, delay, decimal and grouping separators, prefixes/suffixes, easing functions, and scroll-triggered animations, abstracting away the direct CountUp.js instance management. It also ships with TypeScript types, enhancing developer experience in typed projects.
