let link = `<https://api.github.com/user/blocks?page=3>; rel="next", <https://api.github.com/user/blocks?page=3>; rel="last", <https://api.github.com/user/blocks?page=1>; rel="first", <https://api.github.com/user/blocks?page=1>; rel="prev"`;

let result = parseLinkHeader(link);

json_equals(result, {
    first: "https://api.github.com/user/blocks?page=1",
    last: "https://api.github.com/user/blocks?page=3",
