How to pass an array of data from the database to a method?

Question

Node.js

There is this code:

let queryString = 'SELECT * FROM products';
connection.query(queryString, function (err, results) {
        for (let i in items) {
           let products = [{
                "id":items[i].id,
                "name": items[i].name,
                "price": items[I].price
        }];
    }});
    link.addProducts(products);

How to send array products to link.addProducts(products);?

Answer 1

Why not do this in the callback function?

let queryString = 'SELECT * FROM products';
connection.query(queryString, function (err, results) {
        for (let i in items) {
           let products = [{
                "id":items[i].id,
                "name": items[i].name,
                "price": items[I].price
        }];
    }
   link.addProducts(products);
});
