napi_status napi_object_seal(napi_env env,
                             napi_value object); 拷贝

• [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：要封印的对象。

如果 API 成功，则返回 napi_ok。

¥Returns napi_ok if the API succeeded.

此方法密封给定的对象。这可以防止向其添加新属性，以及将所有现有属性标记为不可配置。这在 ECMA-262 规范的 第 19.1.2.20 节 中进行了描述。

¥This method seals a given object. This prevents new properties from being added to it, as well as marking all existing properties as non-configurable. This is described in Section 19.1.2.20 of the ECMA-262 specification.
