title: What are differences between Ext.create() and Ext.define() in SenCha Touch
body: <p>I have been learning SenCha Touch for awhile and still feel confused when trying to create a store.</p>
  
  <p>In the SenCha Documentation, it says to use Ext.create() <a href="http://docs.sencha.com/touch/2.3.1/#!/guide/stores">Example</a>
  I tried and it simply doesn't work.</p>
  
  <p>For the rest of others, I always see people use Ext.define() to create a store and it works.</p>
  
  <p>Now, my question is:
  what are the differences between them and when/how to use either one of them in a right way?</p>
  
  <p>Some demo code is highly appreciated</p>
  
  <p>Thanks a lot my friends.</p>
