Use cases to use classes and OOP are rare in web programming. I mostly find my self creating a class, just to organize a set of functionalities, which are otherwise can be written as simple functions & put together as module.
While writing query builders, I had used classes & inheritance, where there are some low level methods which can be used from all the inheriting classes & inheriting classes would provide their functionalities using the low level methods.
Disclaimer: The code that I write are very simple ones.

If we are only talking about JS, I agree - but web programming also covers PHP, Ruby, Java, Python and many others, all of which are very OOP and utilize classes for almost everything.
Having said that, I too have written classes in JS, just to break it apart again later into simpler modules.
