javaone 2013: «java and javascript - shaken, not stirred»
DESCRIPTION
There is a perception in the Java community that JavaScript is a second-league interpreted language with the main purpose of making Web pages a little prettier. But JavaScript is a powerful, flexible, dynamically typed language. And today language has been experiencing its a revival driven by the interest in HTML5. Nashorn is a modern JavaScript engine available on JVM, and it’s already included with JDK8 builds. This presentation is about building polyglot application with Java and JavaScript.TRANSCRIPT
