210### REPL ([Read Eval Print Loop](https://nodejs.org/docs/latest-v8.x/api/repl.html))

216"The default evaluator will, by default, assign the result of the most recently evaluated expression to the special variable `_` (underscore). Explicitly setting `_` to a value will disable this behavior."
217
218- type `.help` to list commands available in the repl, notice it starts with a dot
219- type `.exit` to exit, note that you still have to press CTRL-C to actually exit, or press CTRL-C (3 times) without typing `.exit` to exit
