6. Factory
Code
Generation
if a class is
suffixed with
factory and it is
passed to the object
manager or in the
constructor and if
the class is not
existing then
magento will create
the class
automatically.

9. Plugin Code
Generation
if a plugin is
defined in the
di.xml, then its
interceptor class is
created in the
var/generation .

12. Proxy Code
Generation
since magento2 uses
DI design pattern
and you can pass the
class reference in
the constructor and
when the class is
loaded is starts a
domino effect to
overcome this
problem magento2
uses proxy design
pattern .
