Format date in ES6
提问by Non
I am formatting a Date, with not momentjs or any other library, just pure JS. And I want to know if there is a way to simplify this with ES6
我正在格式化一个日期，没有 momentjs 或任何其他库，只是纯 JS。我想知道是否有办法用 ES6 简化这个
let currentDate = new Date();
const videosInformation = {
time: currentDate.getHours() + ':' + currentDate.getMinutes(),
date: (currentDate.getMonth() + 1) + '/' + currentDate.getDate() + '/' + currentDate.getFullYear(),
gameId: Math.floor((Math.random() * 5000) + 1)
};
I saw that in the DOM you use something like renderSomething={`something: ${someObj}`}
我看到在 DOM 中你使用了类似的东西 renderSomething={`something: ${someObj}`}
so you don't have to do renderSomething={"something: " + {someObj}}
所以你不必做 renderSomething={"something: " + {someObj}}
is there something I should use to do that kind of format?
有什么我应该用来做那种格式的吗？

There's nothing in ES2015 that added something like strftimeno. There's an ECMAScript internationalisation spec ecma-402which enables localised time:
ES2015 中strftime没有任何东西添加类似no 的东西。有一个 ECMAScript 国际化规范ecma-402可以启用本地化时间：
let [date, time] = new Date().toLocaleString('en-US').split(', ');
const videosInformation = {
time,
date,
gameId: Math.floor((Math.random() * 5000) + 1)
};
Which would give you US localized 8/4/2015and 5:29:19 PMOr if you really want a 24 hour clock:
这会给你美国本地化8/4/2015和5:29:19 PM或者如果你真的想要一个 24 小时制：
new Date().toLocaleString('en-US', {hour12: false})
Then you can do a substring on the time if you want to strip out the seconds.
如果你想去掉秒，你可以在时间上做一个子字符串。
You can read more about date and time at MDT docs.
您可以在MDT 文档中阅读有关日期和时间的更多信息。
