Here, let me put some Javascript in your Java
-
Nashorn is a JavaScript engine implemented fully in Java on the JVM and will be available with JDK 8.
This Project intends to enable Java developers embedding of JavaScript in Java applications

Information is sketchy but this appears to be a new one . . . sort of. According to Wikipedia:The project was announced first at the JVM language summit in July 2011. Nashorn is the German translation of 'rhinoceros', a play on words on Rhino, the name of a JavaScript engine implemented in Java by Mozilla Foundation.

Is there any sensible use-case for writing javascript in java? Between Jython, JRuby, Clojure, Scala and Groovy, I'd say practically every kind of language you want to code in on the JVM is covered. And it's not like anybody has large swathes of business-logic implemented in javascript running server-side in node.js and just wakes up each day with a sigh, thinking "I really love writing javascript server-side, but having to write my own js database drivers is such a pain. I just wish I could use all these java libraries, but without writing java or python or ruby or clojure or groovy or scala or really anything other than javascript."... Right?

A common misconception. Javascript doesn't actually share anything with Java and wasn't even called Javascript to begin with.

I was under the impression Brendan Eich looked at Java when he was developing LiveScript and
stolewas inspired by some of its ideals.There's certainly a lot of overlap - but then since both sprang from C originally, they'd exhibit the same genetic traits.

There is a good application for JS in Java, namely scripting. For larger applications, it's nice to be able to allow users to program the system, and JavaScript is a language that's well-known by many programmers, and isn't that hard to teach to business users. It isn't intended for the original application developers to use it, only the customers who don't have the ability to change the host application themselves, or don't want to expend the effort required to do so.

[quote user="W3C.org"]JavaScript was created in May 1995 by Brendan Eich, then working at Netscape and now of Mozilla.

founder of Netscape. In September of 1995 the name was changed to
LiveScript, then in December of the same year, upon receiving a
trademark license from Sun, the name JavaScript was adopted. This was
somewhat of a marketing move at the time, with Java being very popular
around then.[/quote]

The Dojo that I know is a javascript library that sits somewhere between JQuery and YUI in that it provides DOM manipulation and querying, as well as a set of widgets.

Exactly. It's the same reason Lua has gained any traction in game development. You can script your level logic in a lightweight language, on a lightweight interpreter (less than 1MB, as I recall) and the scripts can be embedded into the level files themselves without needing to be introspected by the engine itself. Not to mention its easier to sandbox so people don't get the bright idea to write custom levels that use system IO to delete the entire file system.

I recall a space invaders clone for Mac that did that. If you destroyed an enemy ship, it would delete a random file from your home folder. If you lost the game, it deleted itself and exited.
-
That'd be awesome if the invaders were each the icons of your files and it just played in attract mode.
Like the silly viruses in Hackers.

Well, yeah, it's called JavaSCRIPT.Reading through the history of Javascript it seems odd -- Javascript was created in the mid-90's as a scripting language for use with Java and Netscape had a "Project Rhino" that was a Javascript engine written in Java. And now, about 18 years later, Oracle, who owns Sun and Java, is announcing a Javascript engine written in Java.
Well, you know what they say, "Everything old is new again".

As someone who puts languages inside other languages that are compiled by yet other languages, that's insane. There might be some cases where it could be useful to me, though...

Idiocy. More idiocy. It doesn't stop there.jsJVM allows execution of Java Bytecode within a web browser without the need for any client side dependancies. [sic]
This brings some interesting questions to light. IIRC, (in theory) Java has certain security features that prevent you from running potentially malicious code online (e.g., using the JNI to call C++, potentially calling __asm in said C++, etc). Doesn't a JavaScript-based JVM completely render all of that moot? Serious question, I might be (and probably am) misunderstanding something here.
OTOH, seems like this would be useful for doing a jsfiddle type deal for compiled languages, but then again there's already ideone et. al.

The JS VM lives within the JS sandbox, so it can't easily access lower level functionality in the same way Java can. It's reasonably safe (as safe as running arbitrary JS), just totally silly.@zelmak said:

You beat me to this.Are there any virtual machines (VM like Hyper-V or VMware, not a JVM) that run on Java? Then you could have a Java application running on a JVM running on JS in a web browser running on Windows running on a virtual machine running on a JVM running in JavaScript running in a web browser.

There's a mod that adds a Lua engine into it, but it would be great if there was a real language in it by default.
