What is Statics in ExtJS

Any class can define static methods, which means we do not need to instantiate the class to call the method;

eg: ClassName.methodName().

To declare a static method or property, simply define it as statics in its class property.

List of static methods for this class. For example:

Ext.define('Computer', {

     statics: {

         factory: function(brand) {

             // 'this' in static methods refer to the class itself

             return new this(brand);

         }

     },

     constructor: function() { ... }

});
