LanguageDetector: destroy() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The destroy() method of the LanguageDetector interface releases the resources assigned to the LanguageDetector instance it is called on and stops any further activity on it. This means that any ongoing and subsequent method calls made on the LanguageDetector will reject with an AbortError.

It makes sense to destroy LanguageDetector objects if they are no longer being used, as they tie up significant resources in their handling.

Syntax

js
destroy()

Parameters

None.

Return value

None (undefined).

Examples

Basic destroy() usage

js
const detector = await LanguageDetector.create({
  expectedInputLanguages: ["en-US", "zh"],
});

// ...

detector.destroy();
