So what is a better way to spend a hot summer day with an ice-cold drink, or dually, a cold winter night with a piping hot drink, than to learn Rx by writing an awesome platform game. In this talk, I will walk you through many of the features of Rx by way of scripting a friendly bug to run across a lavish grass meadow and jump for the stars. In just a few tens of lines of code, we will leverage operators like map
, flatMap
, filter
, scan
