What is NgRx?

NgRx is a reactive state management library for Angular applications, inspired by Redux. It provides a centralized store for managing application state, using actions to trigger state changes and reducers to update the state in a predictable and immutable manner. NgRx promotes unidirectional data flow and helps manage complex application state in a scalable and maintainable way. It also provides features such as effects for handling side effects and selectors for efficiently querying the state.
