title: When to use .toJS() with Immutable.js and Flux?
body: <p>I'm trying to use ImmutableJS with my React / Flux application.</p>
  
  <p>My stores are <code>Immutable.Map</code> objects.</p>
  
  <p>I'm wondering at which point should I use <code>.toJS()</code> ? Should it be when the store's <code>.get(id)</code> returns ? or in the components with <code>.get('member')</code> ?</p>
