Intl.Locale.prototype.maximize()
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 maximize()
method of Intl.Locale
instances gets the
most likely values for the language, script, and region of this locale based on
existing values.
Try it
Syntax
maximize()
Parameters
None.
Return value
A Intl.Locale
instance whose baseName
property returns
the result of the Add Likely Subtags algorithm executed against locale.baseName
.
Description
Sometimes, it is convenient to be able to identify the most likely locale language
identifier subtags based on an incomplete language ID. The Add Likely Subtags
algorithm gives us this functionality. For instance, given the language ID "en", the
algorithm would return "en-Latn-US", since English can only be written in the Latin
script, and is most likely to be used in the United States, as it is the largest
English-speaking country in the world. This functionality is provided to JavaScript
programmers via the maximize()
method. maximize()
only
affects the main subtags that comprise the language identifier: language, script, and region subtags.
Other subtags after the "-u" in the locale identifier are called extension subtags and
are not affected by the maximize()
method. Examples of these subtags
include hourCycle
,
calendar
, and numeric
.
Examples
Using maximize
const myLocale = new Intl.Locale("fr", {
hourCycle: "h12",
calendar: "gregory",
});
console.log(myLocale.baseName); // Prints "fr"
console.log(myLocale.toString()); // Prints "fr-u-ca-gregory-hc-h12"
const myLocMaximized = myLocale.maximize();
// Prints "fr-Latn-FR". The "Latn" and "FR" tags are added,
// since French is only written in the Latin script and is most likely to be spoken in France.
console.log(myLocMaximized.baseName);
// Prints "fr-Latn-FR-u-ca-gregory-hc-h12".
// Note that the extension tags (after "-u") remain unchanged.
console.log(myLocMaximized.toString());
