The format property can accept the following value types:

  • Predefined format
    See the type property description for a list of accepted values.

  • Custom format string
    Use a LDML pattern to specify a custom format. Refer to the following article for more information: Custom Format String.

  • Function
    A function should apply a custom format to a value and return the formatted value as a string. Functions are useful for advanced formatting.

  • Object
    Full format configuration. The object structure is shown in the format API section.
