Review on PetroJS by Matt Larsen

It's easy to use (even for beginners), it has many useful functions that are not available in other JS libraries out there today such as drag&drop or AJAX requests with JSONP support! The documentation could be better but I think they're working hard at improving this aspect of their product so we can have more advanced examples/tutorials online soon :) Currently using PetroJs mainly because its free & open source which means you don't need any license agreement when distributing your code among multiple users / companies - great feature! Also very good community who actively supports eachother via Github issues page + Slack channel where people share knowledge about how things work under-the hood :). Using petrosjs allows us to build web applications without writing server side logic like PHP does while still having all benefits offered by traditional languages used throughout our industry e.g OOP.
