In the vast landscape of React development, developers are armed with powerful tools to navigate challenges effortlessly: the useReducer and useRef hooks. This guide offers a deep dive into these hooks, unveiling their functionalities, adaptable use cases, and advanced methodologies.
What is useReducer ?
