The JS of 2009 was an entirely different language from the JS Netscape originally created. Plus Netscape&#x27;s web server was an evolutionary dead end and a proprietary closed-source product.<p>Node was in part influenced by CommonJS, which tried to unify the various competing but relatively obscure (mostly non-browser) JS environments. To say that it learned nothing from the history of SSJS (or JS environments in general) is, frankly, wrong.<p>That said, Netscape&#x27;s SSJS is entirely unrelated to Node or anything like it[0]. Node lets you write application servers, Netscape&#x27;s SSJS effectively was more like Rhino-meets-JSP or <i>maybe</i> GWT (i.e. the heavy lifting was apparently implemented in Java, not JS).<p>[0]: <a href="http:&#x2F;&#x2F;docs.oracle.com&#x2F;cd&#x2F;E19957-01&#x2F;816-6411-10&#x2F;jsserv.htm" rel="nofollow">http:&#x2F;&#x2F;docs.oracle.com&#x2F;cd&#x2F;E19957-01&#x2F;816-6411-10&#x2F;jsserv.htm</a>
