ECMAScript 6 and Block Scope

[gothburz]

Add block scope to let & const bullet under ECMAScript 6 Styles section or give it its own overview and link.

Seems like this is already covered in 2.3. Am I wrong?

Somewhat, but this issue is looking for a more in-depth section to be added to https://github.com/airbnb/javascript#ecmascript-6-es-2015-styles

I was thinking of adding additional examples like using let in loops under 2.3 itself and referencing it in the es6 list. Does that sound good?

[ljharb]

I guess that could work, but I don't feel like "references" is really the best place for the actual meat of the content.

[nischayv]

That's true. But it seemed to somewhat cover a few concepts already. But I can create a new section entirely for block scope and have stuff like shadowing variables, loops, etc. Would that work?

[ljharb]

Hmm - that might be better, but I'm hesitant to rashly do a big reorg of parts of the guide. If you don't mind the possibly thrown away work, I'd love to review a PR - otherwise I'll think on it more first.

Sounds good!
