Try it
Syntax
js
toString()
Parameters
None.
Return value
The locale's Unicode locale identifier string.
Description
The Locale object is a JavaScript representation of a concept Unicode locale identifier. Information about a particular locale (language, script, calendar type, etc.) can be encoded in a locale identifier string. To make it easier to work with these locale identifiers, the Locale object was introduced to JavaScript. Calling the toString method on a Locale object will return the identifier string for that particular Locale. The toString method allows Locale instances to be provided as an argument to existing Intl constructors, serialized in JSON, or any other context where an exact string representation is useful.
Examples
Using toString
js
const myLocale = new Intl.Locale("fr-Latn-FR", {
hourCycle: "h12",
calendar: "gregory",
});
console.log(myLocale.baseName); // Prints "fr-Latn-FR"
console.log(myLocale.toString()); // Prints "fr-Latn-FR-u-ca-gregory-hc-h12"
