babel-noob: Object.values not transpiled by babel?

[elsherbini]

First off, thanks for making this example repo and for making markovjs!

I'm using node v6.11.2
I can run this example fine with npm run-script start:dev

When I build using npm run-script build and try to run with npm run-script start I get the following error:

➜  markovjs-gridworld git:(master) npm run-script start

> [email protected] start /home/josephe/markovjs-gridworld
> node ./lib/index.js

/home/josephe/markovjs-gridworld/node_modules/regenerator-runtime/runtime.js:573
        throw exception;
        ^

TypeError: Object.values is not a function

I can solve this by installing the object.values shim and manually changing lib/index.js. Any idea why object.values doesn't get transpiled using the current defaults?

The reason this happens is that Object.values is a feature from ES2017 spec, which was implemented from node v7 onwards. If you're running v6.11.2, it's only available through harmony flag I think. That said, babel should've taken care of it I think. I'm taking a look at it now.

Also, thanks for the kind words. (:

Yeah, it seems that's what's happening. I just pushed a change in babel preset and inclusion of polyfill, since this code isn't intended to be used in a library setting. Can you see if it works now, @elsherbini ?
