Web sites can function well with both Javascript, and without Javascript. But programmers and companies have to want to do that.

Apple is a good example. It's often accused (especially on HN) of having a web site that is long on flash and short on substance. It's a massive company constantly trying to separate people from their money.

Guess what? apple.com works fine without Javascript.

And it still looks good. Even the pages flogging the latest phones and computers.

Almost any company can do the same. It just takes good managers, and good programmers. But both of those are in short supply these days.
