Optional ReadonlyidThe message ID. If passed, the message ID is taken from this property instead of the message.string.
This property is useful when various messages share the same message string, for example, the editor string in in the editor
and my editor sentences.
Optional ReadonlypluralThe plural form of the message. This property should be skipped when a message is not supposed to support plural forms. Otherwise it should always be set to a string with the English plural form of the message.
ReadonlystringThe message string to translate. Acts as a default translation if the translation for a given language is not defined. When the message is supposed to support plural forms, the string should be the English singular form of the message.
The internationalization message interface. A message that implements this interface can be passed to the
t()function to be translated to the target UI language.
