Advanced React.js Interview Questions: API Integration and Management
Api In React Js Interview Questions
APIs (Application Programming Interfaces) play a crucial role in React.js development by allowing React applications to communicate with other systems or services. They provide a standardized way for applications to access data, perform operations, and exchange information. This enables developers to integrate external functionalities into their applications, such as accessing databases, sending emails, or interacting with third-party services, without having to write complex code themselves.
