Clojure Destructuring Tutorial and Cheat Sheet

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Definition of the Multiple-actor Problem

The Multiple-actor Problem (MAP) occurs in a web application that contains multiple bits of code, each assuming that they are the only actor in the document. The problem manifests when these assumptions conflict with each other.

Some examples:

A web app is written in framework A, then later an analytics script B is added. A makes assumptions about lifetime of elements and handling of events. B is not aware of these assumptions and subtly violates them, causing jank (example)
A web app is written using framework A. Attempting to introduce a widgets built using framework B results in weird errors, because B is violating A's assumptions about control of document state (examples 1, [2](http://stackoverflow.com/questions/254

I would like to propose a lightning talk for the Reactive Conference demonstrating how you can interact with Arduino and/or Raspberry Pi GPIO's using React Native.

Here's is an example video where fellow speaker Brent Vatne controls my arduino device remotely using a sample react native app that can be found here

Thank you, @christopherdro
