Is the if binding in knockout a custom binding?

It's not a custom binding. What you encountered is what knockout's documentation calls a "Virtual Element", it's a binding applied to a piece of code instead of an element. If you want to conditionally evaluate (i.e. bind to your viewmodel) a part of the DOM you can either put it inside a div with an if binding or put it inside comments like those.
Consequently, why are custom bindings important in Knockout.js?
Custom bindings are a powerful and exciting feature that seem to be often overlooked by newcomers to Knockout.js. They are the key to allowing Knockout to gracefully handle complex behaviors and/or control third-party components/widgets.
Accordingly, when to use knockout to assign a value? If you specify bindings without a value, Knockout will give the binding an undefined value. For example: This ability is especially useful when paired with binding preprocessing, which can assign a default value for a binding.
Besides, is there way to tell knockout not to bind descendants?
This is possible. Your binding can tell Knockout not to bind descendants at all, and then your custom binding can do whatever it likes to bind them in a different way. To do this, simply return { controlsDescendantBindings: true } from your binding’s init function.
In addition, how are DOM elements added and removed in knockout?
In a typical Knockout application, DOM elements are dynamically added and removed, for example using the template binding or via control-flow bindings ( if, ifnot, with, and foreach ). When creating a custom binding, it is often desirable to add clean-up logic that runs when an element associated with your custom binding is removed by Knockout.
