ES6 new features development WeChat applet (8)

ES6 adds a lot of new support for internationalization, such as time format, currency format, number format, etc.

Internationalization & Localization (internationalization and localization) refers to modifying the software to adapt to the language, regional differences and technical needs of the target market.

Internationalization refers to the process of designing software to decouple it from specific languages ​​and regions. When software is ported to different languages ​​and regions, the software itself does not require internal engineering changes or modifications. Localization is the process of adding locale-specific information and translating files when porting software.

The Intl object is a namespace of the ECMAScript Internationalization API, which provides precise string comparison, number formatting, date and time formatting. The constructors for Collator, NumberFormat, and DateTimeFormat objects are properties of Intl objects.
