Why trigger is Preferred over Process Builder in Salesforce?

Hello Anuj,

Via process builder we can only perform below actions like:

1. Create a record of any object type
2. Update any related record—not just the record or its parent
3. Use a quick action to create a record, update a record, or log a call
4. Invoke a process from another process
5. Launch a flow—you can’t schedule this action with workflow
6. Send an email
7. Send a custom notification
8. Post to Chatter

If we want to perform any other actions apart from above actions, then we use trigger in Salesforce.
