在哪里可以找到有关在JavaScript中格式化日期的文档？ [关闭]

问题：

I noticed that JavaScript's new Date() function is very smart in accepting dates in several formats. 我注意到JavaScript的new Date()函数非常聪明，可以接受多种格式的日期。

Xmas95 = new Date("25 Dec, 1995 23:15:00")
Xmas95 = new Date("2009 06 12,12:52:39")
Xmas95 = new Date("20 09 2006,12:52:39")

I could not find documentation anywhere showing all the valid string formats while calling new Date() function. 在调用new Date()函数时，找不到任何显示所有有效字符串格式的文档。

This is for converting a string to a date. 这是用于将字符串转换为日期。 If we look at the opposite side, that is, converting a date object to a string, until now I was under the impression that JavaScript doesn't have a built-in API to format a date object into a string. 如果我们从相反的角度来看，也就是将日期对象转换为字符串，直到现在，我仍然觉得JavaScript没有内置的API将日期对象格式化为字符串。

Today, I played with the toString() method on the date object and surprisingly it serves the purpose of formatting date to strings. 今天，我在date对象上使用toString()方法，令人惊讶的是，它用于将日期格式化为字符串的目的。

var d1 = new Date();
d1.toString('yyyy-MM-dd');       //Returns "2009-06-29" in Internet Explorer, but not Firefox or Chrome
d1.toString('dddd, MMMM ,yyyy')  //Returns "Monday, June 29,2009" in Internet Explorer, but not Firefox or Chrome

Also here I couldn't find any documentation on all the ways we can format the date object into a string. 同样在这里，我找不到关于将日期对象格式化为字符串的所有方式的任何文档。

Where is the documentation which lists the format specifiers supported by the Date() object? 列出Date()对象支持的格式说明符的文档在哪里？
