I prefer to draw a distinction between "attacks" that rely on confusing 
the user to direct them to a fake site (I'll call this phishing for lack 
of a better name) and attacks that actively harm you (more traditional 
security exploits). To some degree, phishing attacks are unavoidable due 
to stupid users, and you can make a case that many would be better 
handled not by informing the user of the malicious page switch 
beforehand but rather by indicating that the target of the link is not 
what the link claimed it was. Although success in the latter arena isn't 
great, either.

One point of pedantry I want to bring up: JavaScript the language is not 
the same as the set of JavaScript libraries used in web programming 
(often known as DOM). The set of new additions to this repertoire over 
the past several years has fallen under the terminology of "HTML5" 
(although I know many web engine developers who dislike that term).

The source of vulnerabilities is often in libraries, not languages; most 
of the security problems in Java that I can think up are not in the core 
VM but rather in the expansive set of libraries that make up the 
standard library. Similarly, JS's core language isn't the source of most 
problems but rather the DOM. In a similar vein, Flash and NaCl have 
problems simply because they allow access to rather less well-secured 
libraries.

The only way you could get rid of these vulnerabilities would be to 
freeze the allowed access and the implementation except for bug and 
security fixes and then wait for 20 years (think TeX). And that's not 
going to happen.
