Websites doesn't require JavaScript, what really needs JavaScript are Singe-Page-Web-Apps-Somethings with anti-patterns like infinite scrolling. You get two things in return, a "super duper" fast web and a more secure web-browser. For example Amazon supports usage without JavaScript very well. Another experience is Stackoverflow, things like the preview and highlighting doesn't work. The highlighting can be added with server-side code but this will cost some CPU-Time - and it is not your CPU-Time. It is their CPU-Time? There is tiny feature I would appreciate in HTML-Engines "copy link to location" instead of using JavaScript - but there is this usable hierarchical address-bar a the top (which Google tries to hide) which already serves this purpose.
I'm not against JavaScript. JavaScript is just a tool but I ask the question if good websites require it? Hackernews uses 134 lines of JavaScript, this is alredy nearly nothing. Can you imagine using Hackernews without JavaScript?
My webbrowser (WebKitGtk) provides a permission panel for every website:
* advertisements
* notifications
* password
* location
* microphone
* webcam
* media
A first step would be adding there JavaScript, too? Maybe some nasty Cookie-Dialogs will disappear as consequence. But that is not a loss?
