Description: Kotlin coroutine builders are functions that allow the creation and management of coroutines, which are a form of asynchronous and concurrent programming. Among the most commonly used builders are ‘launch’ and ‘async’. ‘Launch’ is used to start a new coroutine that does not return a result, while ‘async’ is used to start a coroutine that returns a value, allowing tasks to be executed concurrently. These functions are part of the Kotlin coroutine library, which facilitates writing asynchronous code in a more readable and maintainable way. Coroutines allow developers to write code that can suspend its execution without blocking the thread it is running on, resulting in better resource utilization and a smoother user experience. Additionally, coroutines are lightweight compared to traditional threads, allowing thousands of them to be created without a significant performance impact. In summary, coroutine builders are essential tools in Kotlin for efficiently and effectively handling concurrency and asynchrony.
