        let title = subscriber.getTitle(feedhref);
        if (!options.feedtitle){
            if (title === undefined || title === ""){
                commandline.input("Title: ", createFeed, { argCount: "+"});
            }
            else{
                createFeed(title)
            }
        else{
            commandline.input("Change title \'" + title + "\' ? [y,N]",
                              getTitleFromUser,
                              { argCount: "1" });
        }

        function createFeed(args){
            if (typeof(args) === "string") title = args;
            lvmsvc.createLivemark(
                subscriber.getFeedFolderId(),
                title,
                iosvc.newURI(loc, null ,null),
                iosvc.newURI(feedhref, null, null),
                -1
            );
        }

        function getTitleFromUser(args){
            if (args[0].length === 0
                || "" + args[0] === "N"
                || "" + args[0] === "n"
                || "" + args[0] === "y"){
                    if ("" + args[0] !== "y") createFeed();
                    else
                        commandline.input("Title: ", createFeed, { argCount: "+" });

how about:

        function getTitleFromUser(args){
            let arg = ("" + args[0]).toLowerCase();
            if (arg.length === 0 || arg === "n" || arg === "y"){
                    if (arg !== "y") createFeed();
                    else
                        commandline.input("Title: ", createFeed, { argCount: "+" });
