FYI, the <a href="https://jaxenter.com/graalvm-nashorn-interview-147115.html" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">interview</a> is well worth reading.</p> <p style="margin: 10px 0 0 0">FWIW, I agree with the overall conclusion: it doesn't make sense to build a new community around Nashorn (or expand the existing community around Rhino). I'm convinced that GraalVM is better in every respect.</p> <p style="margin: 10px 0 0 0">The real purpose of this (jira) comment is to push back a little bit on the notion that Nashorn deprecation is a long-term issue. As you know, V3.4 adds a boatload of scripting capability. It would be unfortunate if V3.4 were to ship without a good story about scripting. Best case scenario is that a deployment based on Java 11 could choose to use graal.js instead of nashorn by configuration. If that can be done without an extra download, so much the better.</p> <p style="margin: 10px 0 0 0">This is not so farfetched. The GraalVM libraries (which include JavaScript by default) ship with Java 11. In fact, those libraries have been included in the distribution since Java 9. GraalVM is not vaporware. Twitter, for example, is using the graal JIT compiler in production (instead of the C2 compiler) to optimize their extensive Scala codebase.</p> <p style="margin: 10px 0 0 0">For me, the biggest win using graal.js over nashorn is that the former supports ECMAScript 6+. A deployment with any significant investment in scripting is much better off with an ES6 codebase, or so I claim. Essentially ES6 is a whole new language (which is A Good Thing since the previous versions are riddled with "Bad Parts" as you know).</p> </td>
