The evil ES2015!!!
Let me turn it over for you.

function template(config) {
  var self = this;
  Object.keys(config).forEach(function (key) {
    self[key] = config[key];
  });
}
function factory() {

}

factory.create = function (config) {
  return new template(config);
}
var instance = factory.create({
  title: 'instance1',
  method: () => {
    console.log(this);
  }
});
instance.method();

function template(config) {
  var self = this;
  Object.keys(config).forEach(function (key) {
    self[key] = config[key];
  });
}
function factory() {

}

factory.create = function (config) {
  return new template(config);
}
var instance = factory.create({
  title: 'instance1',
  method() {
    console.log(this);
  }
});
instance.method();
