NgOnInit [Initialize app components here]

This is the entry point of any angular application, we do the basic scaffolding here

Watch for changes in the form

We watch for change and if a change occurs we publish it along with a sequence no to keep track of the form data and prevent stale packets

Handle simple text data from form controls

Later in this course I will also talk about transferring images and videos, for now this will suffice

Angular's magical patch value

Patch value allows us to modify a specific controls of the form without resetting other controls, unlike setValue()

Subscribing to socket

Here we have various events defined that the socket can emit or listen to.
