Kotlin Coroutines
Kotlin Coroutines is a library for asynchronous and concurrent programming in Kotlin, providing a lightweight and structured way to handle background tasks, network calls, and UI updates without blocking threads. It simplifies complex asynchronous code by using suspending functions and coroutine builders like launch and async, making it easier to write, read, and maintain compared to traditional callback-based or thread-based approaches.
Developers should learn Kotlin Coroutines when building Android apps, backend services with Kotlin, or any Kotlin-based project requiring efficient asynchronous operations, as it reduces boilerplate, prevents callback hell, and improves performance by avoiding thread blocking. It is particularly useful for handling network requests, database operations, and UI interactions in a non-blocking manner, enabling responsive and scalable applications.
