What is Coroutine Scope and how is t...

In Kotlin coroutines, a CoroutineScope and CoroutineContext are closely related concepts, but they serve different purposes:

CoroutineScope

• A CoroutineScope is a construct that defines the lifetime and context of a coroutine[1][3].
• It provides a way to launch coroutines and manage their lifecycle[1].
• CoroutineScope is an interface that defines a single property, coroutineContext, which returns the CoroutineContext that defines the scope in which the coroutine runs[1][3].
• The best ways to obtain a standalone instance of the scope are CoroutineScope() and MainScope() factory functions[3].
• The key part of custom usage of CoroutineScope is cancelling it at the end of the lifecycle to cancel all the coroutines that might still be running on behalf of it[3].

CoroutineContext

• The coroutine context includes a coroutine dispatcher (CoroutineDispatcher) that determines what thread or threads the corresponding coroutine uses for its execution[2].
• The dispatcher can confine coroutine execution to a specific thread, dispatch it...
