17,352 PointsWhy the bracket syntax in Op?
I don't understand the bracket syntax [Op.gte]
below. Why not just Op.gte
? I know it doesn't work without the brackets, but not understanding why.
(async () => {
await db.sequelize.sync({ force: true });
try {
// ... All model instances
const movies = await Movie.findAll({
attributes: ['id', 'title'],
where: {
releaseDate: {
[Op.gte]: '2004-01-01' // greater than or equal to the date
}
},
});
console.log( movies.map(movie => movie.toJSON()) );
} catch(error) {
...
}
})();```
