Strange tokens in javascript
<p>There are several tokens in <a href="http://www-archive.mozilla.org/js/language/js20-1999-02-18/tokens.html" rel="nofollow">this page</a> that I have no idea what are used for in Javascript. Those are "->", "::", "..", "...". What are they used for? Or are they just some kind of vestigial feature that never got mainstream?</p>
