Conditional function, compatible with React's JSX precompiler

react.if.js

React.if = function(cond, trueCallback, falseCallback) {
	if(cond && typeof trueCallback === 'function') {
		return trueCallback();
	}
	else if(!cond && typeof falseCallback === 'function') {
		return falseCallback();
	}
};

// Example usage

var thisIsTrue = true;

{React.if(thisIsTrue, function() {
  return (<p>True!</p>);
}, function() {
  return (<p>False!</p>);
})}
