I think the problem is punctuation; reading that sentence it looks like &quot;Web frameworks [that] are no longer supported[.] In JavaScript we have seen Backbone, knockout, angular, ember, and react in rapid succession...&quot; Which is a true statement, though you&#x27;re right that it looks as though the implication is that they&#x27;re no longer supported when in fact it&#x27;s simply that the older frameworks are losing momentum and mindshare.
