Data Fetching
Data fetching is the process of retrieving data from external sources, such as APIs, databases, or files, for use in applications. It involves making network requests, handling responses, and managing data state to ensure applications have the necessary information to function. This concept is fundamental in web and mobile development, enabling dynamic content and real-time updates.
Developers should learn data fetching to build interactive applications that rely on external data, such as social media feeds, e-commerce product listings, or real-time dashboards. It is essential for creating responsive user experiences, handling asynchronous operations, and integrating with backend services or third-party APIs. Mastery of data fetching techniques helps optimize performance, manage errors, and ensure data consistency in modern applications.
