Is there a REPL like iPython for Nodejs?
I've been looking for "ipython for node" for years and here's how I would answer your question:
No.
Is there any kid of "repl + extra features" (like showing docs, module autoreload etc.), like iPython, but for Nodejs?
And I mean something that runs locally & offline. This is a must. And preferably to work both in terminal mode and have an optional nicer GUI on top (like iPython + iPythonQT/Jupyter-qtconsole).
The standard Nodejs repl is usable, but it has horrible usability (clicking the up-arrow cycles through the repl hisoty by line instead of by multi-line command, as you would expect any sane repl to work for interactively experimenting with things like class statements), and is very bare-bones. Every time I switch from iPython to it it's painful. A browser's repl like Chrome's that you can run for node too by starting a node-inspector debug session is more usable... but also too cumbersome.
