Best source code formatter for Javascript? [closed]

I've been digging through Stack Overflow as well as a number of Google searches, and I cannot find a satisfactory code formatter for JavaScript.

I have found several related tools, such as syntax highlighters and pretty-printers, but I am looking for a tool that I can ideally create a wrapper for in Eclipse and simply run from the menu bar. Hence, if any Java-based ones are available, that is a big plus. Free and/or open-source is preferred as well.

I am looking for something that my development group can use to maintain a consistent code style.

Edit: Thanks to kRON for linking to the format customizations page.

In one breath: Aptana Studio! Yes, it's Java based and free (Eclipse, as standalone or plugin).

You can also customize the formatting.

The link above results in 404 -- this looks like the current page aptana.com/products/studio3.html – Amadavat 3/6, 2015 at 15:15

This is by far the best I've come across: http://jsbeautifier.org/

Available as an online tool, or on the command-line using node.js or python. The source code is available.

If you already use Eclipse, I recommend you to try Aptana, you can install it as an Eclipse Plugin.

For Eclipse IDE you can use JavaScript Code Formatter based on Goolge's Style Guide
For IntelliJ IDEA you can use the same js code formatter xml file , but previously you have to install a special plugin Eclipse Code Formatter Plugin, which solves the problem of maintaining a common code style in team environments where both IDEA and Eclipse are used

If you also need Java programming I can recommend 'IntelliJ IDEA'

It offers excellent JavaScript formatting and refactoring out of the box.

Have you tried jsfiddler. It's great for trying things out with Javascript. Built in JSLint & something called Tidy. Not sure whether that infers jstidy Piotr Zalewa is the guy who wrote it. May be worth giving him a Tweet @zalun to confirm.
