+name: XMLHttpRequest
+description: The `XMLHttpRequest` API makes HTTP requests. It's the predecessor to `fetch()`. Also known as XHR.
+spec: https://xhr.spec.whatwg.org/
+# https://caniuse.com/xhr2 is not linked here. It's for a subset of the API that
+# is baked into our definition of XHR. It's too old to split out.
