This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The error() method of the Response interface returns a new Response object associated with a network error.
Note: This is mainly relevant to ServiceWorkers; the error method is used to return an error if you so wish it. An error response has its type set to error.
Note: An "error" Response never really gets exposed to script: such a response to a fetch() would reject the promise.
var errorResponse = Response.error();
None.
A Response object.
TBD (does not yet appear to be supported anywhere).
