Examples

js
function onLanguageDetected(langInfo) {
  for (const lang of langInfo.languages) {

    console.log(`Percentage is: ${lang.percentage}`);
  }
}

let text = "L'homme est né libre, et partout il est dans les fers.";

let detecting = browser.i18n.detectLanguage(text);
detecting.then(onLanguageDetected);
