.editor : a tmp full editor to run multi-line code
ctrl+d : to finish above editor

Node.js concept
npm install: will localized all modules for local project, like python lib but local copy for each project (like python, module has version history, some project may have different version, but seems various js lib version have bigger compatibility change compared to python modules)
