This attribute is defined in the Fetch API, where it is exposed as the {{domxref(\"Request.destination\")}} property.\n\nWe could think of it, roughly, as the way the returned resource would be used.\n\nFor most {{glossary(\"replaced elements\")}}, the value of the header names the element that this resource will be used for, such as iframe, object, audio, or video. A value of image indicates that the resource will be used as an image referenced by a replaced element such as an HTML {{htmlelement(\"img\")}} element, a CSS {{cssxref(\"background-image\")}} property, an SVG {{svgelement(\"image\")}}, or any other place in the web platform that use images loaded from subresources.\n\nSome other interesting destination values include\n\ndocument : The request is for a new document that is the target of a top-level navigation (for example, the user clicking a link in the page or submitting a form).\n\nscript : The resource will be used as a script loaded from an HTML {{htmlelement(\"script\")}} element or a call to {{domxref(\"WorkerGlobalScope.importScripts()\", \"importScripts()\")}} in a web worker.\n\nempty : The request does not have a defined destination: among other possible causes, this is the value given if the request is the result of a {{domxref(\"Window.fetch()\", \"fetch()\")}} call.\n\nFor the complete set of possible values, see the {{HTTPHeader(\"Sec-Fetch-Site\", \"reference page\", \"\", \"nocode\")}} for this header.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
