TypeScript at Google
Web shouldn't end up this way. Web was designed for sharing documents. Webs and webapps now are sluggish and take soooo much RAM. I have a pretty fast computer with 16GB RAM but running all these webapps with Megabytes of javascript is bringing back -5years experience and can fill up my RAM. I know it is still improving but webapp developers are also quick with abusing every performance gain often for unwanted and unneded functionality. For example CSS animations for every mouse over, material clicking highlights are terrible, terrible design decisions which occassionally even spin up my laptop fan.
