Why is jQuery not integrated within the browser

Question

Why isn\'t jQuery intergrated into browsers, so there would be no need to have to reference it on your site, and instead, the browser just notices the jQuery used, and every

Answer 1

All JavaScript libraries should be integrated into a browser, which therefore uses a global storage for them (like Google, for example) so that when one library is updated, it will also be updated on that one storage center. That would be one way how, whatever the browser version, libraries won't be outdated. As for the dollar mark, I figure some function should be created by a browser like ..

 use_library( 'jquery' ){
     // my jquery code
 }

 use_library( 'prototype' ){
     // my prototy[e code
 }

However, since integrating JavaScript libraries will only be effective when the browser won't load it via internet on each request, rather only on a library update and then only once, too, it needs to have some sort of a "cool" system that checks for a new library once a day or so, making as little request as possible.

My 2 cents.
