Response.ok

The ok read-only property of the Response interface contains a Boolean stating whether the response was successful (status in the range 200-299) or not.

Value

A boolean value.

Response.json()

The json() method of the Response interface takes a Response stream and reads it to completion. It returns a promise which resolves with the result of parsing the body text as JSON.

Syntax

});

Copy to Clipboard

Parameters

Return value
