【筆記】JavaScript編碼規範- 逗號和分號,javascript分號

不要再語句前面使用逗號。

// badvar story = [once, upon, aTime];// goodvar story = [once,upon,aTime];

不要有多餘逗號:這會在IE6、IE7和IE9的怪異模式中導致一些問題;同時,在ES3的一些實現中,多餘的逗號會增加數組的長度。在ES5中已經澄清(source)

// badvar hero = {firstName: 'Kevin',lastName: 'Flynn',};var heroes = ['Batman','Superman',];// goodvar hero = {firstName: 'Kevin',lastName: 'Flynn'};var heroes = ['Batman','Superman'];


分號使用樣本。

// bad(function() {var name = 'Skywalker'return name})()// good(function() {var name = 'Skywalker';return name;})();

1:13 And the evening and the morning were the third day.
