a trigger handler is the starting point to ‘handle’ complex logic set into a trigger. Creating a class defined as MyObjectTriggerHandler can help to design a modular set of reusable objects which manage all the operations to be done by a trigger.

Mainly we use TriggerHandler to manage events like before update , before insert, etc . write one more class called TriggerHelper , in this classs we write methods to implement logic like when one field is updated do this do that, etc .
The important point in writing all these classes is to keep one trigger for one object and avoid conditions like recursive calls etc.
