Plugin with javascript intellisense and autocomplete support?

I 开发者_运维问答know this question has been asked previously, but they were asked a long time ago and answers to those questions weren't satisfactory. So I am asking it again - what is the best eclipse plugin available out there that can provide basic javascript as well as jquery auto-completion and intellisense if possible. I am looking for something other than Aptana Studio here.

I am using eclipse for J2EE developers version 3.6 Helios package (probably it has WTP installed from the start).

In term of pure auto-completion, bugs like 159508, 121871 or 125088 seem to suggests it already exists, even though it doesn't have all the options of a Visual Studio IntelliSense.

However, a more complete version of IntelliSense was available with Aptana (as I reported in 2008), was still the best (in Eclipse world) in 2009, and can be installed as a plugin in an Eclipse (using the p2 update site http://update.aptana.com/install/studio):

See blog post jQuery IntelliSense (code assists) on Eclipse 3.5 (late 2010).

I was going to suggest the WTP - does it lack the features you need? It usually works pretty well for basic Javascript.
