Why Learn RxJava?

 As a beginner using RxJava was bit tough and tricky for me but by the time RxJava made something special in android programming. Specially in using Operators and Threading!

1. Operators:

1. It has powerful operators that make creating observable objects very simple.
2. You can create observables out of lists, arrays, custom data objects, combine multiple observables into one... You can sort, filter, find max and min. The list goes on.

2. Threading:

1. Running tasks on a background thread
2. Retrieving results on the main thread
3. Or visa versa. It doesn't matter. It makes threading incredibly simple. RxJava and RxAndroid is the death of AsyncTask. You'll never use it again.
