A coroutine in Kotlin is a lightweight concurrency design pattern that allows developers to write asynchronous, non-blocking code in a sequential manner. Coroutines enable the suspension of long-running tasks without blocking the execution thread, leading to more responsive and efficient applications.
Unlike traditional threading models, where threads are heavyweight and costly to create and manage, coroutines are lightweight and can be launched in large quantities without consuming excessive system resources. Coroutines leverage cooperative multitasking, enabling multiple tasks to execute concurrently within the same thread.
Coroutines in Kotlin are based on the concept of suspending functions, which are functions that can be paused and resumed at specific suspension points without blocking the underlying thread. This allows for the seamless integration of asynchronous programming paradigms into Kotlin applications.
