I tried Eclipse many times over last decade. Always used for few weeks before code highlighting and completion drove me insane due to multiple crashes, hangups and slowdowns.<p>Trouble with elaborate &#x27;correct&#x27; solutions starts when you need another thing. I don&#x27;t think support in Eclipse for .cjsx or PureScript or whatever is coming soon. I won&#x27;t wait 10 years till they get it &#x27;right&#x27;. I&#x27;ll use Atom to get the 95% right in few months.
