switchMap vs concatMap: Key Differences and Use Cases

It has been a long time that I haven’t written any blog posts. Lets start with again with this one. RxJava is a great library and has a lot of operators. It is powerful but power comes with its disadvantages if you don’t know how to use it. You need to learn each operator in details otherwise it may not work as you expected. Sometimes, you study the operators in details, time passes over it, and then you remember the main functionality but you forgot some minor details which are important in some use cases. Then you understand that you need to check documentation again 😀 That happened to me as well.
