Using bitwise operations to filter results based on user selected filters in javascript

I am a web developer for a software house in Athens, Greece. I currently work almost exclusively with the Microsoft stack of languages, and most prominently with C#. However, I have worked extensively with PHP in the past, dabbled in C and C++ while doing my MSc, and for my pet projects I usually resort to Python, if a GUI is not necessary. That said, I'm also usually the guy that oversees/designs the database schema for each new project at work.

When not in front of the computer, I enjoy watching and helping my two young daughters grow up. Sometimes I do that while in front of the computer too.
