While studying Node, I encountered a problem and asked a question.
View page is using Handlebars.
The controller stores the value as a variable, gets the value from router.get, and sends it to the View page.
However, when used on the View page, the value is not displayed.
Controller Code
exports.boardData = async (req, res, next) => {
    const { id } = req.query;
// If there is an id value
            if(id) {
                db.start.query('SELECT * FROM board WHERE id = ?', [id], async (err, result) => {
                    if(!result) return next();
            
                    result[0].date = moment(result[0].date).format("YYYY년 M월 D일 HH시 mm분");
                    req.board = result[0];
                    checkBoard = result[0].userid;
                    updateCount = result[0].count;
                    if(refreshCheck === false) updateCount = result[0].count + 1;
                   
                    refreshCheck = true;
                    * Here is the problem. *
                    db.start.query('SELECT * FROM comment WHERE boardid = ?', [id], async (err, result) => {
                        if(!result) return next();
                        req.comment = result;
                        req.commentCount = result.length;
                        console.log(req.comment);
                        console.log(req.commentCount);
                    });
    
                    db.start.query('UPDATE board SET count = ? WHERE id = ?', [updateCount, id], async (err, result) => {
                        if(!result) return next();
                    });
                });
            }
}
Here I want to store and send values as req.comment, req.commentCount.
router.get Code
router.get('/boardRead', authController.boardData, (req, res) => {
    res.render('boardRead', {
        user: req.user,
        board: req.board,
        userid: req.userid,
        comment: req.comment,
        commentCount: req.commentCount,
    });
});
View Page Code
<div class="container mt-4">
        <div class="jumbotron" style="border: none;">
            <table class="board-table table table-sm table-hover table-striped text-center" style="border: 1px solid rgba(0, 0, 0, 0.2);">
                <thead class="thead-light">
                    <tr>
                        <td scope="col">comment {{commentCount}}</td>
                    </tr>
                </thead>
                <tbody>
                    {{#if comment}}
                        {{#each comment}}
                           <tr>
                              <td>{{this.comment}}</td>
                              <td>{{this.name}}</td>
                           </tr>
                        {{/each}}
                    {{/if}}
                </tbody>
            </table>
        </div>
    </div>
User or board brings values, but not comments. I did the same way, but I am wondering why I can't bring it to the View page. When I print it with console.log, the value is printed properly.
