Updated for modern versions of Node Redis

[guyroyse]

Example as coded does not function. A simple update to support async/await and the actual function names that Node Redis 4 uses.

Argh! Linting. Will patch.

The linter is not happy with const and not happy with async. Not sure what else I can do here. I can say—with authority—that the example does not work with Node Redis 4, which is what you get when you run npm install redis as suggested in the comment.

You can keep using var and replace async/await with .then().
