Selectors in React Redux
- Data Extraction: Selectors are functions that extract specific pieces of data from the Redux store.
- Abstraction Layer: They act as an abstraction layer between your components and the store, making it easier to access and manipulate data.
- Memoization: Selectors are memoized, meaning they cache the results of their computations. This improves performance by preventing unnecessary re-renders when the same data is requested multiple times.
- Encapsulation of Logic: They encapsulate any logic needed to derive derived data from the store, such as filtering, sorting, or combining multiple pieces of data.
- Reusability: Selectors promote code reusability by allowing you to define data retrieval logic once and reuse it across multiple components.
Explain Selectors in React Redux
Selectors in React Redux serve as efficient filters for accessing specific data from the Redux store. They encapsulate logic for data retrieval, optimizing performance, and promoting code reusability. By using memoization, selectors cache results to prevent unnecessary re-renders, thus enhancing overall application efficiency. They make efficient in the process of accessing and transforming data, contributing to improved development efficiency and code quality.
