为了弥补Date的缺陷,很多程序员着手开发一些开源的库来绕过对Date的直接使用,比较优秀的npm库如 date.js 、moment.js,但 Date 的问题始终困扰着Javascript这门语言的进一步发展,于是TC39组织开始了对Date的升级改造,他们找到了 moment.js 库的作者,Maggie ,由她来担任新特性Temporal的主力设计。 感兴趣的同学可以去...
moment(String); When creating a moment from a string, we first check if the string matches known ISO 8601 formats, we then check if the string matches the RFC 2822 Date time format before dropping to the fall back of new Date(string) if a known format is not found. var day = momen...
Also, date/time libraries can only take you so far. All date libraries work by giving you access to convenient data structures to represent a DateTime. If you are sending and receiving data through a REST API, you will eventually need to convert the date to a string and vice versa because...
ISO 8601 allows a "Z" appended to the time to designate UTC (i.e. instead of "+00:00", "+0000", or "+00"). Javascript'sDate.toISOStringuses this "trailing Z" format, which is why I noticed that it's missing from the current implementation ofstrtotime ...
Intl.DateTimeFormat: Provides date and time formatting Intl.RelativeTimeFormat: Provides language-sensitive easy-to-read phrases for dates and timestamps These constructors take two optional arguments: the locale and an object with options to customize the output. Here’s an example: let rtf = ...

Date#format( format, utc ) Formats the date as a string, according to the format pattern given. A variable to be substituted starts with a %, then optionally a '-' to stop it from being 0-padded to a fixed length (if applicable), then a character to indicate the desired part of th...
