Does Google track my coding habits to show Google ads in their search if i use any their hosted JavaScript framework?

...Or is there some other reason for them to host these? What is the benefit 开发者_如何学编程to them from hosting these frameworks?

Google wants the web to be as rich as possible, the more apps and sites, the more possible ad revenue for them.

No, they cannot track you by the frameworks, they are fetched once across all sites that use that url and then cached on the client. If say 20 sites all references a js file hosted on google, the user only gets it once. Hosting your own...if it's an intranet app, yes do that, if not then reference google, lower your load times a bit most likely.

Also, google has peering agreements, bandwidth is very, very cheap for them.

Its all about the war between Microsoft and Google. Google wants web applications to replace desktop ones.
