Extend a base config

[jstcki]

It's kinda hard to keep up with all eslint features, so maybe we should just extend eslint:recommended? Then it also becomes more clear which are our overrides.

Cf. https://github.com/rackt/eslint-config-rackt

How about depending on and extending https://github.com/airbnb/javascript/tree/master/packages/eslint-config-airbnb, since they're actively maintaining it. We've already used it as a base when we started this config. We made some changes for our own needs but 95% is airbnb style. Another advantage would be that they also maintain a style guide and that their config is in line with that.

FWIW, that would also solve #6.

I might look into this, because we would actually need to be able to solve #6 in our current project where Purescript interop is only available through ES5, not ES6. Because the foreign function interface is also the place where the compiler can help the least and where most bugs are to be expected, a solid linter would be necessary. We also have other projects that are purely ES5 and that we will maintain for a while longer.

Is there anything I need to know with regards to trying to solve this issue? Still not sure whether tackling this is worth it, but if the problem keeps bugging me, it might be 😄
