Intl.DateTimeFormat.prototype.format()

The format() method of Intl.DateTimeFormat instances formats a date according to the locale and formatting options of this Intl.DateTimeFormat object.

Return value: A string representing the given date formatted according to the locale and formatting options of this Intl.DateTimeFormat object.

Return value: Note: Most of the time, the formatting returned by format() is consistent. However, the output may vary between implementations, even within the same locale — output variations are by design and allowed by the specification. It may also not be what you expect. For example, the string may use non-breaking spaces or be surrounded by bidirectional control characters. You should not compare the results of format() to hardcoded constants.
