Difference between moment.toString() and moment.toISOString()
提问by Ramesh Rajendran
I have reading moment.jsdocument, there have a moment.toISOString()function for helps to formats a string to the ISO8601standard.
我有阅读moment.js文档,有一个moment.toISOString()功能可以帮助将字符串格式化为ISO8601标准。
Also there have a another one reason for why we use moment.toISOString()
Also there have a another one reason for why we use moment.toISOString()
moment.toISOString()function using for performance reasons.
moment.toISOString()出于性能原因使用的函数。
I don't know toISOString()the performance best than moment.toString().But only the result was difference while using moment.toString()and moment.toISOString().
我不知道toISOString()比 的性能最好moment.toString()。但只有在使用moment.toString()和时结果有所不同moment.toISOString()。
So my question is.
所以我的问题是。
Why we should use
moment.toISOString()? for performancereasons?And what is the difference between
moment.toISOString()andmoment.toString()?
为什么要使用
moment.toISOString()?出于性能原因?和之间有什么区别
moment.toISOString()和moment.toString()?

You can give a look directly in momentJS source code for such issue :). Here it is.
您可以直接在 momentJS 源代码中查看此类问题:)。 在这里。
export function toString () {
return this.clone().locale('en').format('ddd MMM DD YYYY HH:mm:ss [GMT]ZZ');
}
export function toISOString () {
var m = this.clone().utc();
if (0 < m.year() && m.year() <= 9999) {
if ('function' === typeof Date.prototype.toISOString) {
// native implementation is ~50x faster, use it when we can
return this.toDate().toISOString();
} else {
return formatMoment(m, 'YYYY-MM-DD[T]HH:mm:ss.SSS[Z]');
}
} else {
return formatMoment(m, 'YYYYYY-MM-DD[T]HH:mm:ss.SSS[Z]');
}
}
toStringuse.locale('en').format('ddd MMM DD YYYY HH:mm:ss [GMT]ZZ')which is momentJS source code, executed in JavascripttoISOString()use javascript Date object (this.toDate().toISOString();) which is compile and managed by your browser.
toString使用的.locale('en').format('ddd MMM DD YYYY HH:mm:ss [GMT]ZZ')是 momentJS 源代码,在 Javascript 中执行toISOString()使用this.toDate().toISOString();由浏览器编译和管理的javascript Date 对象 ( )。
Native implementation is ~50x faster, use it when we can
本机实现速度快约 50 倍,尽可能使用它
However, I think such difference is not relevant for a most projects, but now you know. ;)
但是,我认为这种差异与大多数项目无关,但现在您知道了。;)
