var Categories = [
    { "text": "Mobile Recharge", "callback_data": 1 },
    { "text": "Internet", "callback_data": 2 },
    { "text": "Digital Code", "callback_data": 3 },
    { "text": "Tv", "callback_data": 4 }
];

var Categories = [
    [ { "text": "Mobile Recharge", "callback_data": 1 },{ "text": "Internet", "callback_data": 2 } ],
    [ { "text": "Digital Code", "callback_data": 3 },{ "text": "Tv", "callback_data": 4 } ],
];

this is full code

let Categories = [];
bot.hears('🛒 Categories', ctx => {
    db.query(`SELECT * FROM cat WHERE status = 1`, function(error, res) {
        res.forEach(function(row) {
            var cat = { text: row.title , callback_data: row.id }
            Categories.push(cat);
        });
        var InlineKeyboardMarkup = {
            'inline_keyboard': [Categories]
        }
        ctx.reply("Select a Category : \r", {
            "reply_markup": JSON.stringify(InlineKeyboardMarkup)
        });
        Categories = []
    })
})
