Question

Battery.belongsTo(TagType, { constraints: true, onDelete: "CASCADE" });
Tag.belongsTo(TagType, { constraints: true, onDelete: "CASCADE" });
const battery = sequelize.define("Battery", {
id: {
type: Sequelize.INTEGER,
autoIncrement: true,
allowNull: false,
primaryKey: true,
},
voltage: {
type: Sequelize.INTEGER,
allowNull: false,

percetange: {
type: Sequelize.INTEGER,
allowNull: false,
},
});
const tag = sequelize.define("Tag", {
id: {
type: Sequelize.INTEGER,
autoIncrement: true,
allowNull: false,
primaryKey: true,
},
name: {
type: Sequelize.STRING,
allowNull: false,
unique: true,
},
battery: {
type: Sequelize.INTEGER,
allowNull: true,
},
});
//api
const percetangeAndTags = [];
const tags = await Tag.findAll({
include: [
{
model: TagType,
attributes: ["name"],
},
],
});
error.catchError("notFound", tags);
await Promise.all(
tags.map(async (tag) => {
const batteryVoltageValue = await Battery.findOne({
where: {
tagTypeId: tag.tagTypeId,
voltage: { [Op.lte]: tag.battery },
},
attributes: [
[Sequelize.fn("max", Sequelize.col("voltage")), "max"],

});
const battery = await Battery.findOne({
where: {
tagTypeId: tag.tagTypeId,
voltage: batteryVoltageValue.dataValues.max,
},
});
percetangeAndTags.push({
id: tag.id,
name: tag.name,
tag_type: tag.tag_type.name,
percetange: battery?.percetange,
});
})
);
res.status(200).json(percetangeAndTags);
How can I write this code in the most efficient way?
Because the explanation is short, it doesn't accept the question, so I wrote a poem instead of randomly throwing it.

Söz ola kese savaşı söz ola bitire başı
Söz ola ağılı aşı bal ile yağ ede bir söz
