    1. napi_status napi_object_seal(napi_env env,
    2.                              napi_value object);
    • [in] env: The environment that the N-API call is invoked under.
    • [in] object: The object to seal.

    Returns napi_ok if the API succeeded.

    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.
