Update react.js

Adding function with value return

[yarinkos]

@tmacwill , is this addition look fine ?

[tmacwill]

apologies for the delayed response! it looks like this has two <%cursor%> elements—I think you only want one?

I think more about bootstrap functional component like, with the argument as a default return value :
const Headline = ({ value }) => { return {value}; };
But you don't have to accept it,maybe this one is too simple

and return value in this snippet seems redundant as value is not a templated variable. Also it's a little long.
