So one example that we use is for many input fields to have formatting done based on the client and their 'settings'/locale. It's basically just a wrapper around the html 5 input with the different types. So decimal places, right aligned, currency symbol, certain client validation that may be different per customer, etc. At the same time we name those components different than something like < Button /> so that it is very clear it's not just a UI wrapper, it has functionality.
