我正在检查如何以以下格式显示
JavaScript日期：YYYY-MM-DDTHH：mm：ss.sssZ,但是我看到了两种方法：
.toJSON()和
.toISOstring().
他们之间有什么真正的区别吗？
他们之间有什么真正的区别吗？
解决方法
在内部,toJSON()调用到ISOString()如果可用,所以没有区别.
15.9.5.44 Date.prototype.toJSON ( key )
This function provides a String representation of a Date object for use by JSON.stringify (15.12.3).
When the toJSON method is called with argument key,the following steps are taken:
Let O be the result of calling ToObject,giving it the this value as its argument.
Let tv be ToPrimitive(O,hint Number).
If tv is a Number and is not finite,return null.
Let toISO be the result of calling the [[Get]] internal method of O with argument “toISOString”.
If IsCallable(toISO) is false,throw a TypeError exception.
Return the result of calling the [[Call]] internal method of toISO with O as the this value and an empty argument list.
