Tads Basic Game Objects, tabageos, is a JavaScript library for making games and applications. I've been working on it for the past 12 years in my spare time. Originally it was an AS3 library for Flex game making, starting in 2012 I ported it to JavaScript.
One method many may find useful even outside of a game setting is the tabageos.loadSpriteSheetAndStart method. With a little setup you can effectively keep an image from showing up in dev tools using that method. I use it to generally secure sprite sheets for games. One major game released with the library so far is called Idle City Sim 2051. The github has complete games that are open source and there are examples of using each class individually.
