Chapter 1Creating Observables
If you’re brand new to the concepts in observables or just need a refresher, this is the chapter for you. This chapter starts with a sense of where observables conceptually fit in the greater world of JavaScript tools. You’ll build your first project of the book: a stopwatch. A stopwatch may seem simple, but you’ll need to learn several key observable concepts to get it working. Once the stopwatch is up and running, you will prove the reusability of Rx by building a drag-and-drop example from the stopwatch code using the exact same pattern and operators. First things first, though, it’s time for Rx basics.
