Request: integrity property

The subresource integrity value of the request (e.g., sha256-BpfBw7ivV8q2jLiT13fxDYAe2tJllusRSZ273h2nFSE=).

If an integrity has not been specified, the property returns ''.

In the following snippet, we create a new request using the Request() constructor (for an image file in the same directory as the script), then save the request integrity value in a variable:

const myRequest = new Request("flowers.jpg");
const myIntegrity = myRequest.integrity;
