Gzipped source in a high level language can be much smaller than the equivalent bytecode.

That's not why these demos "Hello Framework" demos are 3-7MB though. That's due to the cost of shipping an entire widget system that takes complete responsibility for everything between raw user input to pixels on the screen, without using many of the affordances of browser APIs. This is really awesome for emulation, sandboxing, and preservation of software, but it's not a good route for saving bytes for the user.
