I'm running Eclipse Mars 4.5 with JSDT and it's getting increasingly difficult to use this for JavaScript/Node.JS development, since it doen't recognize modern patterns:

This is because the JavaScript Validator is set to ECMAScript 3.

To my surprise for such an up-to-date release of Eclipse, this dropdown is greyed out and I cannot select 5 or 5.1, let alone 6. ES3 is from 1999 (!).

Am I correct to assume that Eclipse has no considerable JavaScript munity? Other FOSS projects with modern ECMAScript support:

• NetBeans supports ES5.1, ES6 in 8.1
• Atom.io supports ES6

(I haven't used these so I don't know how they pare to Eclipse)

Is Eclipse discouraged for JavaScript development? Or is there actually a well-documented non-hacky go-to plugin for Eclipse to play nice with ES6?

• 1 @Chris I invite you to mention these other options. – Redsandro Commented Apr 8, 2016 at 1:15
• Refer to the duplicate - it mentioned other plugins – Krease Commented Apr 8, 2016 at 1:27
• @Chris The one answer and its ments is all about the same plugin called 'tern'. If this can at the same time be not supporting ES6 and other options, it requires some clarification. – Redsandro Commented Apr 8, 2016 at 1:53

Eclipse Neon will improve a lot support for JavaScript with JST 2.0.0 like :

• support for ES6
• Grunt, Gulp, npm support

You can try too tern.java if you wish advanced pletion, validation where you can use for eslint, jshint which support ES6. See Tern Linter section for that.
