• [in] env：调用 Node-API 调用的环境。

  ¥[in] env: The environment that the Node-API call is invoked under.

• [in] object：从中检索属性的对象。

  ¥[in] object: The object from which to retrieve the properties.

• [in] property_count：properties 数组中的元素数。

  ¥[in] property_count: The number of elements in the properties array.

• [in] properties：属性描述符数组。

  ¥[in] properties: The array of property descriptors.

如果 API 成功，则返回 napi_ok。

¥Returns napi_ok if the API succeeded.

此方法允许在给定对象上高效定义多个属性。属性是使用属性描述符定义的（参见 napi_property_descriptor）。给定一组此类属性描述符，此 API 将一次设置一个对象的属性，如 DefineOwnProperty() 所定义（在 ECMA-262 规范的 第 9.1.6 节 中描述）。

¥This method allows the efficient definition of multiple properties on a given object. The properties are defined using property descriptors (see napi_property_descriptor). Given an array of such property descriptors, this API will set the properties on the object one at a time, as defined by DefineOwnProperty() (described in Section 9.1.6 of the ECMA-262 specification).
