I've spent the last 20 years writing HTML, JavaScript and CSS by hand for rather well known large web facing companies. I've lived and fought through ALL the fads from XML data islands, through jQuery, Angular etc. I know this intimately well to the point of spending hours debugging IE specific issues and having MS connect cases open due to browser bugs. I've opened 20 odd Chrome defects as well. And at this moment I'm prototyping an interface for something in Bootstrap that lives inside Electron
What I have is battle scars and a right to bitch.
