Polymer handles i18n through mixins, computed bindings, and external translation files.
// i18n behavior/mixin
const I18nMixin = (superClass) => class extends superClass {
_t(key) {
const translations = { 'hello': 'Hallo', 'world': 'Welt' };
return translations[key] || key;
}
};
// In template: [[_t('hello')]], [[_t('world')]]
