Small, fast, simple and streaming project scaffolder for myself, but not only. Supports hundreds of template engines through the @JSTransformers API or if you want custom `render` function passed through options

'use strict';

module.exports = function (x) {
	if (!x) return false;
	if (typeof x === 'symbol') return true;
	if (!x.constructor) return false;
	if (x.constructor.name !== 'Symbol') return false;
	return (x[x.constructor.toStringTag] === 'Symbol');
};
