Incorrect precedence for regex and comment highlighting

[mngyuan]

If a line contains a slash and a comment, the plugin highlights the text from the slash to the comment as a regex, then fails to highlight the comment.

var result = 1 / 2; // this is a comment, but it won't be highlighted
var block = 2 / 3; /* this also will consider /3;/ as a regex */

default vim syntax highlighting also gets this behavior wrong

Yes, I see it too. The regex to match the JavaScript regexes is quite complex. I'll suggest to stick with // as your line comments for now.
