Can someone explain to me whats the difference between with(GlobalScope){ launch{} } and GlobalScope.launch{}? All I can find is: "You can use with() in order to avoid the repetition of the GlobalScope receiver" but I don't really get it.
Thanks in advance

You can't launch a coroutine by using

with(GlobalScope) {
  // . . . 
}

You are gonna have to add launch like so

with(GlobalScope) {
  launch {
    // . . . 
  }
}

While you can just launch a new coroutine like so

GlobalScope.launch {
   // . . . 
}

Yes, thanks I editet my question so it makes more sense.
What is the usecase of using with(GlobalScope){ launch{} } ?

[andylamax]

just use GlobalScope.launch you are not getting any benefit by using with if all you are trying to do is just launch a corountine

[andylamax]

also avoid the use of GlobalScope create your own scope if possible

The with function is a stdlib function, not a coroutine function. Your examples will behave exactly the same.

with - stdlib function that takes two parameters. One becomes the receiver for the second lambda parameter. For your case if you need to call launch several times its will be less code if use with.
