해결책

// my solution
String.prototype.render = function (options) {
  return this.replace(/(?:\$\{)([\.\w]+)(?:\})/g, (match, $1) => {
    if ($1.includes('.')) {
      var p = $1.split('.');
      return p.reduce((p, n) => p[n], options);
    }
    return options[$1];
  })
}

String.prototype.render = function (options) {
    with(options) {
        return eval('`' + this + '`')
    }
}
