Reaktive VS kotlinx.coroutines

There is another library developed by me - Reaktive. This one was done partly during the working hours and partly during my spare time. It is used in the apps (traces can be found in the APKs) and I'm totally fine of it being company's property.

I will say on the topic of multiplatform, rxjava isn't directly supported. However there is a multiplatform Rx library called reaktive which has way better testing support compared to coroutines at the moment. although if multiplatform is something you're interested in doing I would start the project off rather than do it later to save time in the long run. If you're interested, the mpp Todo sample is a good example demonstrating a lot of everything.

Now, let's consider an example. For instance, let's create a Kotlin/JVM project with kotlinx.coroutines library as a dependency.

Greetings community, I just submited a PR to Kotlin coroutines with two additional operators :

The harder parts of Kotlin are going to be things like kotlinx.coroutines, but that's just a library, not a core part of the language. It's about as hard to learn as a comparable library in another language, like the Task Parallel Library in .NET.

Kotlin has coroutines that are supported by the language and implemented by a library (the implementation remains platform-dependent): kotlinx.coroutines and a sandbox environment is available here to try it out.

That said, since it seems like you're doing UI stuff (Android?), you're best off doing all of the UI code in coroutines, using Dispatchers.Main as a context (as provided by one of the platform-specific coroutine libraries), since this will guarantee that your UI code will be safely run in the UI thread.
