title: Understanding what Flux Facebook is trying to solve
body: <p>Just watched <a href="https://www.youtube.com/watch?v=nYkdrAPrdcw&amp;list=PLb0IAmt7-GS188xDYE-u1ShQmFFGbrk0v#t=621" rel="nofollow">this YouTube video</a>.</p>
  
  <p>Jing here gives an example of the ghost new message count problem and how they fixed it using Flux. What specific series of events would lead to such problem? Is this an issue because of multi-threaded environment? Putting simpler code structuring aside, is flux kind of architecture needed in a single threaded environment like the web browser Javascript?</p>
