Exploring coroutine builders, scopes, and dispatchers

In this section, you will learn how to use coroutine builders and explore coroutine scopes and dispatchers. Coroutine builders are functions that are used to create coroutines. Coroutine scope is the scope with which the coroutines run. Dispatchers specify in what thread the coroutine will run.

In the previous section, you created a coroutine with launch. However, there are other ways to create coroutines. Coroutine builders are the functions that you can use to create coroutines. To create a coroutine, you can use the following Kotlin coroutine builders:

• launch
• async
• runBlocking
