Using my shitty javascript skills to add Slack nicks to real names

slack-nicknames.js

function addNicks() {
    $(".message_sender").map(function() {
        var name = $(this).data("x-name");
        if (!name) {
            name = $(this).text();
            $(this).data("x-name", name);
        }
        var href = $(this).attr("href");
        if (href) {
            var nick = href.slice(6);
            $(this).text(name + " (@" + nick + ")");
        }
    });
}

// ugggghhhh
setInterval(addNicks, 250);
