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 isArrayish(obj) {
	if (!obj) {
		return false;
	}

	return obj instanceof Array || Array.isArray(obj) ||
		(obj.length >= 0 && obj.splice instanceof Function);
};
