At my company, we still use the same thing to create high performance web sites. HTML, CSS, JavaScript, SQL and our favorite programming language which I won't go into. We don't even consider anything else because we've been there and done that (whatever one needs) years ago. The only time we give any thought to any framework or library is when the client requires it for some existing interface and we can't get around it. But we will make an effort to scrape off such things wherever possible cause that's our job: high performance at low cost.
