Classes

Bidi
-
This provides utility methods for working with bidirectional text. All
of the methods are static, and are organized into a class primarily to
group them together for documentation and discoverability.
-
BidiFormatter

Bidi stands for Bi-directional text. According to
Wikipedia:
Bi-directional text is text containing text in both text directionalities,
both right-to-left (RTL) and left-to-right (LTR). It generally involves text
containing different types of alphabets, but may also refer to
boustrophedon, which is changing text directionality in each row.

DateFormat
-
DateFormat is for formatting and parsing dates in a locale-sensitive
manner.

Intl
-
The Intl class provides a common entry point for internationalization
related tasks. An Intl instance can be created for a particular locale
and used to create a date format via
anIntl.date(). Static methods
on this class are also used in message formatting.

Used primarily for currency formatting, this number-like class stores
millionths of a currency unit, typically as an Int64.
