Intl.Locale.prototype.baseName
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2020.
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"
