How to implement exception handling in asynchronous coroutines?

In Kotlin coroutines, to handle exceptions, you can use try-catch blocks within the coroutine itself or apply special constructs such as CoroutineExceptionHandler.

Example with try-catch inside a coroutine:

launch {
    try {
        val result = someSuspendFunction()
        println(result)
    } catch (e: Exception) {
        println("Error: ${e.message}")
    }
}

If the coroutine is launched via launch, unhandled exceptions are passed to CoroutineExceptionHandler:

val handler = CoroutineExceptionHandler { _, exception ->
    println("Handled exception: ${exception.message}")
}

GlobalScope.launch(handler) {
    throw RuntimeException("Error in coroutine")
}

Thus, you can flexibly manage errors in asynchronous code.
