Remove Grunt

[FredrikNoren]

Grunt is pretty dead by now. We could probably refactor the build script into something much simpler in just plain JS

I like how mocha testings, bumping up dependencies, transpiling and other actions have a single point of entry. Do you really mean to get rid of Grunt? or replace with other solutions such as gulp or maybe even a make file?

[FredrikNoren]

I think most people just do plain .js build files these days (no gulp, no makefile). With async/await it's pretty easy to do multi-step asynchronous operations.

What about babel? should we step away from that?

[FredrikNoren]

Bable is only used to make sure the backend code is compatible with old node versions right? If we removed it, the min version would be 6? Or 7?

[jung-kim]

I think our code base will be at node 6 and considering client side code isn't es6 I think it is more safer. Honestly, babel is something that is seemingly becoming an industry standard that I don't personally have a strong affinity for so I don't really mind it but I would like for us to understand that it means we are limiting backward compatibility if we decided to keep es6 on server side.

[FredrikNoren]

Personally, I'm perfectly fine with only supporting the "live" versions of node; 6 is the current LTS. Either way, removing grunt doesn't necessarily mean we have to remove Babel

[jung-kim]

I'd be okay with just supporting node 5+ as well. Hopefully there are not many complaints...
