What features of error handling do you know when working with Kotlin Coroutines?

Error handling in Kotlin Coroutines has its own features related to asynchrony and coroutine structure:

• Coroutine hierarchy and cancellation: Errors in child coroutines can cancel the parent coroutine if not handled.
• CoroutineExceptionHandler: A special handler for unhandled exceptions in coroutines, which can be assigned when creating a coroutine.
• try-catch inside coroutines: You can use a regular try-catch to handle exceptions within suspend functions.
• SupervisorJob: Allows child coroutines to operate independently so that an error in one does not cancel others.

Example of using CoroutineExceptionHandler:

val handler = CoroutineExceptionHandler { _, exception ->
    println("Caught $exception")
}

GlobalScope.launch(handler) {
    throw AssertionError("My custom error")
}

Thus, it is important to choose the right error handling strategy depending on the context and structure of coroutines.
