Dynamic loading in Extjs

Question

I have a question about Extjs

I have read the official document on Sencha doc but I have some confusions about the dynamic loading.

What is the difference between new X() and Ext.create('X')? Which should be used and when?

Any answer are very appreciated.

Answer 1

never ever use new in ExtJS. if you use dynamic loading with Ext.create('X') ExtJS will check if the class X is already loaded and will load it before internally create the class with new.
