Simple tool that listens for keys to be hit in a certain order and calls a callback if the pattern matches.

keyPatternLogger = new KeyPatternLogger(
  {
    pattern: ["a", "b", "c"],
    callback: function() {
      console.log("It worked!");
    }
  }
)

Accepts hash of parameters, pattern and callback.

• pattern is an array of keys, can be as many or as few as you like
• callback is a method with code that you want to execute when the pattern occurs.

Note: Modifier keys can also be checked for, e.g. "meta+a"

If the pattern consists of multiple keys, e.g. ["a", "b", "c"] the user needs to hit a, b, and c, in that order. If they hit any other key in-between, it isn’t a match.

If you only want to listen for one key, e.g. ["a"], that’s totally fine too. The callback will be called every single time someone hits the a key.

If you want to stop the KeyPatternLogger from listening for matches, you can call keyPatternLogger.stop() (and start it again with keyPatternLogger.start())
