JavaScript can be a scary place where we create and change variables at will and while code can be written very quickly, it can be side-effect prone and hard to debug & maintain down the line. In this talk we’ll explore the concepts of imperative vs. declarative code, and do a live demo of Reactive Programming using RxJS in Angular.

No matter what the JavaScript framework flavor of choice is, a good understanding of reactive programming and state management helps us write better code that is more closely tied to business logic, is easier to read, easier to debug, and easier to scale.
