RxJava vs Kotlin Coroutines: Which Should I Use?

What are the main differences between RxJava and Kotlin Coroutines?

RxJava is a library for reactive programming, while Kotlin Coroutines are built into the Kotlin language for asynchronous programming. RxJava uses observable streams, whereas Coroutines use suspending functions.

Which one is easier to learn for a beginner?

Kotlin Coroutines are generally considered easier for beginners due to their simpler syntax and integration with Kotlin's language features.

Can you give me an example of how to use both?

Sure! In RxJava, you might use an Observable to emit items, while in Coroutines, you would use a suspend function to perform asynchronous tasks. Would you like a code snippet?

Yes, please provide a code snippet for both.

Here's a simple example: In RxJava, you might write Observable.just(data).subscribe(...), and in Coroutines, you would use suspend fun fetchData() { ... } to fetch data asynchronously.
