下面这段JS代码，什么语法检测工具可以发现错在哪里？

var asdfsdf = {
	sdfsdf: [
		['aaaaa', 'aaaaa'],
		['adsfsadf', 'wfwfwef'],
		['--sdf-','asdfasdf">asdfsadfsdf>'],
		['afds'],
		['asdf'],
		['sfdaf'],
		['adf',['adsf','sdf','asdf'], 'sdf:sdf']
		['-df--'],
		['sfd', 'dsf:sdf'],
	]
};

[‘adf’,[‘adsf’,‘sdf’,‘asdf’], ‘sdf:sdf’] 这句后门的逗号没写，但是jshint语法检测为何没有报错？
