exitandquitcould be variable names so we have.exit. we could do what python does and show a warning when those keywords are asked for without being assignedwe could do what python does and show a warning when those keywords are asked for without being assigned
that's better, or you could forbid people to define global variable named "quit" or "exit" only in REPL just like what ipython already did and that is considered user friendly.
Agreed that this isn't a great user experience.
ReferenceError: quit is not definedI'd assume the chances of someone typing
quitorexitby themselves into the repl, when they're not defined, and not wanting to quit the repl should be vanishingly rare.- changed the title

Reacted by mary marchiniWould you all be opposed to prompting for clarification? The repl makes you type
CMD-Ctwice to exit.You could do something like:
> exit Did you mean '.exit' [Y/n]?
It could default to YES, so, if they simply press return, they’ll exit. If they say NO, it will proceed to run as if exit is a reference.
Benefits:
- No addition of restricted words (quit or exit may be a function that the user defined)
- No conditional logic based on what’s defined in the scope (which may cause confusion)
- A noninvasive reminder of the current way to exit the repl

And why nodejs doesn't know that?
