Intl.Locale.prototype.baseName
The baseName
accessor property of Intl.Locale
instances returns a substring of this locale's string representation, containing core information about this locale, including the language, and the script and region if available.
Description
baseName
returns the language ["-" script] ["-" region] *("-" variant)
subsequence of the unicode_language_id grammar. It only includes information explicitly specified in the constructor, either through the locale identifier string or the options object.
The set accessor of baseName
is undefined
. You cannot change this property directly.
Examples
Basic Example
js
const myLoc = new Intl.Locale("fr-Latn-CA"); // Sets locale to Canadian French
console.log(myLoc.toString()); // Prints out "fr-Latn-CA-u-ca-gregory"
console.log(myLoc.baseName); // Prints out "fr-Latn-CA"
Example with options in the input string
js
// Sets language to Japanese, region to Japan,
// calendar to Gregorian, hour cycle to 24 hours
const japan = new Intl.Locale("ja-JP-u-ca-gregory-hc-24");
console.log(japan.toString()); // Prints out "ja-JP-u-ca-gregory-hc-h24"
console.log(japan.baseName); // Prints out "ja-JP"
Example with options that override input string
js
// Input string indicates language as Dutch and region as Belgium,
// but options object overrides the region and sets it to the Netherlands
const dutch = new Intl.Locale("nl-Latn-BE", { region: "NL" });
console.log(dutch.baseName); // Prints out "nl-Latn-NL"
