Are these two code snippets equivalent?

val job = SupervisorJob()
val lifecycleScope = CoroutineScope(Dispatchers.Main + job)

lifecycleScope.launch { }

val job = SupervisorJob()
val lifecycleScope = CoroutineScope(job)

lifecycleScope.launch(Dispatchers.Main) { }

I would say not entirely equivalent -- the two `lifecycleScope`s obviously have different final contexts, but the code in launch will be run in the same way, if that was the question

[Vincent Williams]

ok that was my main question. Why would the context be different? would it need to be

lifecycleScope.launch(Dispatchers.Main + job) { }

[Vincent Williams]

ie: if I cancel job in the second snippet, it still cancels that launch correct?

[octylFractal]

the context is different in that any launch (or async, etc.) would use the Main dispatcher by default in the first one, but only the single launch in the second one uses Main by default

[octylFractal]

the job cancellation would still work the same

[octylFractal]

only the coroutineContext[CoroutineInterceptor] would differ -- no other element

[Vincent Williams]

ok perfect! thank you!
