JSX Params check for '{...}'

[allenmanning]

One thing for consideration is the common error of putting quotes around jsx params. This seems to be a common source of errors. I can't think of a good reason why you would want to do this, and if you do you could always assign a variable like this

let myString = '{...}'

<element param={myString}/>

I've never seen this, is it really common?
In any case, this would be impossible to detect due to its ambiguity with valid strings.
