Blocking vs. Non-Blocking Kotlin Coroutines Suspending functions CoroutineScope Coroutine builders Coroutine dispatcher Coroutine start Conclusion What are coroutines? Coroutines have been around for quite a time now. They are in-fact one of the ideas which helped develop multitasking operating systems. A coroutine in trivial most is a subroutine or function generalisation which in non-preemptive environment (operating system or OS in short) can voluntarily yield the CPU time so that other such sub-routines can use it for themselves without losing the results of previous computations and then can conti...

This post is continuation of Kotlin series. If you haven't read my introductory post about Kotlin then I'll recommend you reading previous post before continuing with this one. Kotlin is a modern language. I've been working with kotlin for past few months now and I just love it. In todays post I'll talk about three features of kotlin viz. Higher Order Functions, Lambdas and Extension methods. This post also contains working code showing of each of these features. You are free to copy the code and experiment with it. If you haven't already setup kotlin on your system then you can run code using kotlin online playground . Higher order fu...

Photo by wu yi “A language that doesn't affect the way you think about programming is not worth knowing.” ―Alan J. Perlis World was nice and there was only assembly(“real programmers code in assembly”) but then one day out of blue he (hey! don't look at me like that I too don't know his name) came and said let there be compilers and interpreters(line by line) that will translate languages easy to read(uh! nah not really) and write into assembly to make programming fun again and that gave birth to an era of exotic new programming languages called procedural programming languages. Procedural programming languages were doing fine but after some time lot's of programmer started loosing their objects because of stateless functions which globally caused chaos. Seeing all this made him angry. So he said, “Procedural languages, I command you to treat everything as an ‘Object’ which will have it's own properties(attributes) and behavior(methods)”. They respond...
