What is the entity of the coroutine context?

The coroutine context is a set of elements that define the behavior of a coroutine. It includes:

• Job: Manages the lifecycle of the coroutine (cancellation, completion).
• CoroutineDispatcher: Determines the threads or thread pools where the coroutine will be executed.
• CoroutineExceptionHandler: Handles uncaught exceptions within the coroutine.
• CoroutineName: Used for debugging (displayed in logs).

The context is created when the coroutine is launched and can be combined from different contexts.

Example of creating a combined context:

import kotlinx.coroutines.*

fun main() = runBlocking {
    val context = Dispatchers.Default + CoroutineName("MyCoroutine") + CoroutineExceptionHandler { _, throwable ->
        println("Caught: $throwable")
    }
    launch(context) {
        println("Running in MyCoroutine with dispatcher ${coroutineContext[CoroutineDispatcher]}")
        throw IllegalStateException("Something went wrong")
    }
}
