Framer Motion is a powerful open-source library for creating animations and interactive user interfaces in React applications. It’s designed to make complex animations and transitions easy to implement, allowing developers to add polish and dynamism to their web projects without a lot of extra code. At its core, Framer Motion provides a declarative API for defining animations and gestures, which means you can describe what you want to happen (e.g., move an element from one position to another) in a clear and concise manner, without having to worry about the underlying implementation details. One of the key features of Framer Motion is its support for physics-based animations, which can give your UI elements a more natural and lifelike feel.
