i18next-scannerusingkeyswithvariables的中文翻译为i18next-scanner在使用带有变量的key时的问题

对于带有变量的key，可以使用${}来将key作为字符串模板。例如：

const i18next = require('i18next');
const scanner = require('i18next-scanner');

const variable = 'world';
const key = `hello_${variable}`;

i18next
  .init({
    lng: 'en',
    debug: true,
    resources: {}
  });

scanner({
  // other config options ...
  keySeparator: false, // by default: '.'
  sort: false, // by default: true
  func: {
    list: ['t'], // by default ['i18next.t']
    extensions: ['.js', '.jsx'] // by default: ['.js']
  },
  trans: {
    component: 'Trans', // by default: 'i18n'
    i18nKey: 'i18nKey', // by default: 'i18nKey'
    defaultValues: [], // added: see next section
    // fine-grained fallbacks for keysPerNamespaces
    fallbackKey: (ns, value) => value,
    // added: for pluralization support
    fallbackPlural: true
  }
}, (err, keys) => {
  // Here, if key = "hello_${world}", it would return "hello_${world}" as key string
  console.log(keys);
});
