title: Dynamic Getters/Setters with ES6 Classes
body: <p>I've been searching the web and found some solutions but not an easy to implement solution for dynamic setters in an ES6 Class.</p>
  
  <p>What I'd like is to have is a dynamic setter inside my class so that when I add any possible property from the outside, a certain operation will occur on that property. I've read on Proxies and that does seem to be the reasonable solution for this. However, I wasn't able to understand how to correctly implement it and would like your guys' input on this.</p>
  
  <p>Thanks!</p>
