As someone who has tried to find a way to help content authors develop and maintain big web sites by creating (HTML) components for years, I\'m really excited to see web compone
I never heard of standardising javascript frameworks. However with HTML5 some parts that used to need javascript frameworks in earlier versions of HTML have now been added as a standard feature to HTML5 (for example the tag , rounded borders, shadow effects, ...), which is a first step in solving what you are mentioning.
To be honest I don't think that this is ever going to happen, or at least not in the near future. All those frameworks out there have their own purposes, advantages and disadvantages. Until you can build a huge javascript library that somehow combines them all there will always be different libraries used all over the web.
Another important point is the competition between the different libraries that keeps the javascript market growing and come up with new innovations. IF you would make a standard javascript library that all would use, you would also eliminate the competition between the different frameworks that keeps innovation and progress going.
