Your comment is correct, but in this context is is completely off...
This like compare apples to satellites, when having a conversation about seahorses.
Of course i can make an application that spits output to the a web browser, but this requires network activity, (literally the most inefficeint least reliable thing in coding now that > 60% of all traffic is coming over mobiel networks).
So you can't tell me that offloading 95% of those "web requests" for silly things that complex applications need to perform, ont a javascript based app, that now only has to send 1 in 20 requests to your server for display calculation is less efficient.
Don't flame just to flame friend :)
