Javascript frontend with a Javascript backend

Is it possible for a web site?

Javascript to process queries on the sever, Javascript to render the page, Javascript database, Javascript compiler, Javascript editor.

All made in Javascript.

Implementation-wise, you fat shit, i.e. a fully JS compiler.

TCO is improbable in JS. __noSuchMethod__ is useless (just throw an exception), and why not just use this:
function Anus () {
  this.haxus_the_great = 5;
}
Anus.prototype = {
  get hax() { return this.haxus_the_great; },
  set hax(v) { this.haxus_the_great = v * 90; },
  get anus() { return "This is an anus"; }
};
It works perfectly well with alert (anus.hax); and anus.hax = 100.1;
