let flatten = (nestedList) => {
		let result = [];
		let fn = function(target, ary) {
			for (let i = 0; i < ary.length; i++) {
				let item = ary[i];
				if (Array.isArray(ary[i])) {
					fn(target, item);
				} else {
					target.push(item);
				}
			}
		}
		fn(result, nestedList) return result;
}
