Add exit support to repl

[tracker1]

Just a nice to have feature request. It would be nice, if one could simply type exit and enter into the repl, and have it process.exit(0)

This would match up with most command-line interface repls, from bash to cmd, etc... and is second nature to type in. I'm not sure if this has been debated, as I didn't see an issue regarding this. As it stands, I can type exit\n faster than I can press ctrl+c twice.

Hopefully this feature is doable, and others can agree on the usefulness.

Alternatively to an immediate process.exit(0) would be process.nextTick(() => process.exit(0)) so that pending outputs can finish out.

.exit does what you want, I think.

Or use Ctrl+d

As noted, there are existing solutions to this. Simply supporting exit would not work because that would mean reserving that keyword which is not really ideal (and .exit has existed for a long time and it is only one more character).
