Framer Motion
Framer Motion is a popular open-source React library for creating smooth, declarative animations and gestures. It provides a simple API for animating components with support for spring physics, keyframes, and layout animations, making it easy to add complex motion effects to React applications. It is widely used for building interactive user interfaces with fluid transitions and engaging visual feedback.
Developers should learn Framer Motion when building React applications that require sophisticated animations, such as interactive dashboards, product showcases, or mobile apps with gesture-based navigation. It is particularly useful for projects where performance and smooth animations are critical, as it leverages React's reconciliation and supports server-side rendering. Use cases include animating page transitions, creating drag-and-drop interfaces, and implementing micro-interactions to enhance user experience.
