 * An object that contains string translations for multiple languages.

 * When English does not exists it falls back to the first defined language.
 *
 * ### Example ###
 *

 *         "en", "Hello World!",
 *         "ru", "Привет мир!"
 *     );
 *
 *     let value1 = values.get('ru'); // Result: "Привет мир!"
 *     let value2 = values.get('pt'); // Result: "Hello World!"
