Async/Await
Async/await is a syntactic feature in many modern programming languages that simplifies writing asynchronous, non-blocking code. It allows developers to write asynchronous operations in a style that resembles synchronous code, making it easier to read and maintain. This is achieved by using the 'async' keyword to define functions that return promises and the 'await' keyword to pause execution until a promise resolves.
Developers should learn async/await when working with I/O-bound operations, such as network requests, file system access, or database queries, to avoid blocking the main thread and improve application responsiveness. It is particularly useful in web development for handling API calls, in server-side applications for managing concurrent tasks, and in any scenario where performance and scalability are critical, as it helps manage complex asynchronous workflows more cleanly than traditional callback or promise-based approaches.
