Syntax

relativeTimeFormat.resolvedOptions()

Return value

A new object with properties reflecting the locale and number formatting options computed during the initialization of the given RelativeTimeFormat object.

Description

The resulting object has the following properties:

locale

The BCP 47 language tag for the locale actually used. If any Unicode extension values were requested in the input BCP 47 language tag that led to this locale, the key-value pairs that were requested and are supported for this locale are included in locale.

style

The length of the internationalized message. Possible values are:

• "long" (default, e.g., in 1 month)
• "short" (e.g., in 1 mo.),
• or "narrow" (e.g., in 1 mo.). The narrow style could be similar to the short style for some locales.

numeric

The format of output message. Possible values are:

• "always" (default, e.g., 1 day ago),
• or "auto" (e.g., yesterday). The "auto" value allows to not always have to use numeric values in the output.

numberingSystem

The value requested using the Unicode extension key "nu" or filled in as a default.

Examples

Using the resolvedOptions method

var de = new Intl.RelativeTimeFormat('de-DE');
var usedOptions = de.resolvedOptions();

usedOptions.locale;          // "de-DE"
usedOptions.style;           // "long"
usedOptions.numeric;         // "always"
usedOptions.numberingSystem; // "latn"
