About jsx curly braces variable

[monochrome-yeh]

refer to https://facebook.github.io/react/docs/jsx-gotchas.html

const test = 'test';
<div>{'First &middot; Second'}</div>
<div>{test}</div>

I would like find the rule to do like these:
(add space before/after curly braces)

const test = 'test';
<div>{ 'First &middot; Second' }</div>
<div>{ test }</div>

however, I haven't found that yet,
maybe I've missed keywords.

Does jscs has this relevant rules ?

I don't think so, if it's not on there we don't have it, sorry
