Often we are looking new html5 or js features at caniuse.com to determine if we can use this feature or not for my production code.
caniuse.js -> It will detect everything in browser side. It can tell us if I can play mp3/ogg/wav music, use server sent events, geolocation, or if i can use drag and drop feature. Returns true or false. You can check many things. Type it in your browser console
