"JavaScript, the most common language for implementing interactive web pages, instead of Java"
Oh here we go again. I'm experiencing this pain at work right now - so many contemporary approaches to software development assume you're developing web pages FFS. In fact most enterprise software development consists of complex heavy-weight processing server-side, with some Javascript/HTML client-side to provide a user interface.
"JavaScript is lighter weight and easier to pick up than Java"
Having used both, I find this assertion hard to believe.
