[aida] [Pharo-project] A trend and an unfair comparison about js everywhere

Here we have IMHO an advantage and opportunity with Smalltalk for the
web apps: *JavaScript is very hard for complex apps*. For the reasons
others already expressed: lack of version control, strange errors,
inadequate debugging, etc. That's why they are all that preprocessors
like CoffeeScript and new MS TypeScript out there - to ease development
and specially maintenance of any bit more complex JS web app.

So, Aida plan is to use Amber to *emit* JavaScript code to the client
while still preserve all the power and beauty of developing in classical
Smalltalk environment: browsers, debuggers, inspectors, version control
etc. And specially to develop and long-term maintain very complex web
apps, which is currently near to impossible in plain JavaScript. Such
Aida webapp will be still deployed to the server but with emitting JS to
the client the app will actually run quite autonomous on the client,
with just syncing data changes back to the server, while all UI
interactions will happen locally on the client.

Another Aida plan is to bring to the web all that Smalltalk has in 80's
already on UI front: MVC, dependency mechanism with real-time updating
all views, which are dependent on some data change, etc.

And how MVC GUI architecture ideas from 80's look like? Read from in
this book (which is from 90's actually):
