react-transition-group offers low-level primitives for managing component transitions in React. It provides tools for defining enter, exit, and appear states, triggering animations based on these lifecycle events. Rather than dictating specific animation styles, it focuses on managing component state and timing, giving developers full control over the animation implementation using CSS transitions, CSS animations, or JavaScript animations. This library serves as a solid foundation for building custom transition and animation effects in React applications.
