What is the difference between

(1..3).asFlow().onEach { number -> println("$number") }.collect()

And

(1..3).asFlow().collect { number -> println("$number") }

Why would I want to use onEach when I can use collect directly?

[araqnid]

They are equivalent. Some people may prefer one to the other. Or, for example, using onEach followed by launchIn rather than collect

[flosch]

No difference, as you already said.
onEach is most of the time used in combination with a tail .launchIn(CoroutineScope) instead of a surrounding Coroutinescope.launch { ... }

[araqnid]

jinx!

[Carrascado]

Oh ok, I wondered If I was missing something, thank you!

you have the possibility to call other operators like onStart or catch when using onEach

[flosch]

you have the possibility to call other operators like onStart or catch when using onEach

You can also use those operators with collect

[jean]

right of course, I was thinking of “after” calling collect or onEach , I should I specified that :)
