2. Import the assets/js/theme/{relative-path}/b3lang.js to assets/js/theme/global.js using the code below:

  // other code

  + import b3lang from '{relative-path}/b3lang';

  export default class Global extends PageManager {
    onReady() {
      // other code
      window.b3themeConfig = window.b3themeConfig || {}

      // config the lang key: To config the lang key, B3 will use the browser language keys to find the language config from window.b3themeConfig.locale automatically if the lang key is not found from the js. The default language (English) will be used for the storefront if all the browser language keys don't match one of the keys in window.b3themeConfig.locale.
      + window.b3themeConfig.lang = 'en'
      + window.b3themeConfig.locales = b3lang
      // other code
    }
  }
