Like A Surgeon – Dissecting a completely Functional-Reactive JavaScript app for the very first time

Reserve your seat
Netta Bondy

Today we have the ability to write fully Functional-Reactive code in JavaScript, using RxJS. However, in our day-to-day life we often use RxJS alongside other libraries and patterns that make our life easier, but also distance us from pure Functional-Reactive Programming (FRP).
What would an app that has been written completely in RxJS, and in-line with the principles of FRP, look like?
In this talk we will examine such an app, and use it to understand what truly functional-reactive code in JavaScript looks like, and what are the principles that underlie it.


What are the key takeaways from this talk?

This talk will answer the following questions:

  • What are the main concepts of Functional-Reactive Programming, and how are they expressed in JavaScript/RxJS code?
  • What is the structure of an FRP app, and how is it different from how we usually write code?
  • How can we integrate more FRP concepts in our everyday code?
