/**
 * Allows developers to copy a response and modify its `headers`, `status`,
 * or `statusText` values (the values settable via a
 * [`ResponseInit`]{@link https://developer.mozilla.org/en-US/docs/Web/API/Response/Response#Syntax}
 * object in the constructor).
 * To modify these values, pass a function as the second argument. That
 * function will be invoked with a single object with the response properties
 * `{headers, status, statusText}`. The return value of this function will
 * be used as the `ResponseInit` for the new `Response`. To change the values
 * either modify the passed parameter(s) and return it, or return a totally
 * new object.
 *
 * @param {Response} response
 * @param {Function} modifier
