Use the Airbnb style in the source

[gaearon]

Following @DenisIzmaylov's suggestion in #95, I propose we adopt the Airbnb styleguide and change the style if it differs from Airbnb.

If everyone's on board with this, I'd accept a PR that:

• adds as many Airbnb-enforcing style rules to .eslintrc as possible
• changes the source and the README to match the styleguide

Thoughts?

Can't we just use their eslint rules?

[gaearon]

I guess we can

[hzoo]

So you want to extend their rules? "extends": "eslint-config-airbnb",

You can also use the jscs autofix feature to fix most of the whitespace rules
jscs docs examples scripts src test --preset=airbnb --fix.
Can probably do a PR later for that.

[DenisIzmaylov]

I'm agreed to @hzoo about eslint-config-airbnb. Yesterday I had tested "extends" feature of ESLint and it wasn't successful. Now I found that I used old (0.20) version which may not support this feature correctly. I will try with latest (0.23).

[DenisIzmaylov]

Ok, in 0.23 it's working nice. But might be we have to upgrade some rules?

Finished by PR #121

[ooflorent]

Can we close it now?

[DenisIzmaylov]

I think no. We have to update README examples to match this code style (point #2 from this issue).

[gaearon]

I'd say let's close because README is going to be rewritten anyway.
