Notable tech: Emmet (snippets, HTML autocomplete), Engine.IO (web-sockets), MsgPack (message serialization), RuSHA (browser-based SHA1), Tern (code analysis, AST etc), Acorn (JS code analysis, faster than Tern)
I switched to cloud-dev about a year ago. Took some getting used to, but I can't imagine going back to local-dev now.
