Async/await
Software Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Async/await is a syntactic feature in JavaScript that allows writing asynchronous code in a synchronous style. It simplifies the handling of promises by using the async keyword for functions and await for pending promises.
Example in context
“We refactored our API calls to use async/await, which made the data fetching code much more readable.”
“API çağrılarımızı async/await kullanacak şekilde yeniden düzenledik, bu da veri çekme kodunu çok daha okunabilir hale getirdi.”
Where engineers use it
Async/await is commonly used in JavaScript functions that perform I/O operations like network requests. Engineers use it to avoid callback hell and write cleaner asynchronous logic in both frontend and backend code.
