moment.js返回三月和八月最後一天的「無效日期」

Question

當我將年，月，日作爲字符串傳遞到moment.js日期構造函數以獲取該月的最後一天時，它返回「Invalid date」三月和八月：

moment(["2022","0","31"]).toISOString() 
"2022-01-31T06:00:00.000Z" 
moment(["2022","1","28"]).toISOString() 
"2022-02-28T06:00:00.000Z" 

//March 
moment(["2022","2","31"]).toISOString() 
"Invalid date" 

moment(["2022","3","30"]).toISOString() 
"2022-04-30T05:00:00.000Z" 
moment(["2022","4","31"]).toISOString() 
"2022-05-31T05:00:00.000Z" 
moment(["2022","5","30"]).toISOString() 
"2022-06-30T05:00:00.000Z" 
moment(["2022","6","31"]).toISOString() 
"2022-07-31T05:00:00.000Z" 

//August 
moment(["2022","7","31"]).toISOString() 
"Invalid date" 

moment(["2022","8","30"]).toISOString() 
"2022-09-30T05:00:00.000Z" 
moment(["2022","9","31"]).toISOString() 
"2022-10-31T05:00:00.000Z" 
moment(["2022","10","30"]).toISOString() 
"2022-11-30T06:00:00.000Z" 
moment(["2022","11","31"]).toISOString() 
"2022-12-31T06:00:00.000Z" 

然而，當我指定month參數的整數，這些日期的工作：

//March 
moment(["2022",2,"31"]).toISOString() 
"2022-03-31T05:00:00.000Z" 

//August 
moment(["2022",7,"31"]).toISOString() 
"2022-08-31T05:00:00.000Z" 

我不知道爲什麼，當我經過一個月的參數爲發生這種情況字符串與整數？

原來，升級到最新版本的moment.js修復了它。

老斷裂的例子（v2.7.0）： https://jsfiddle.net/1Lwauz1t/1/

最新版本的例子（v2.18.1）： https://jsfiddle.net/dsadkpsa/

下面是上面的鏈接被執行的代碼的jsfiddle：

console.log(moment(["2022","2","31"]).toISOString()); 
console.log(moment(["2022",2,"31"]).toISOString()); 
console.log(moment(["2022","7","31"]).toISOString()); 
console.log(moment(["2022",7,"31"]).toISOString());
