The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

#Control Structures

##If statement

Kotlin if statement should look familiar with other language

fun main(args : Array<String>) {
 val total = 10

This is a quick guide to Kotlin programming language. The previous part of this guide is here

#Object Oriented

fun main(args : Array<String>) {
  class local (val x : Int)
  
  val y = local(10)
 println("${y.x}")
