Javscript：左括号之前和最后一个括号之后没有双引号

Question

The issue is related to the extra double quotes " character in the products array in between the opening [ and the first { , as well as between the closing } and ] , this comes from the JavaScript variable called "products" being printed as a string. So the question is how to get that variable to print without the surrounding double quotes?

let products = '';
        for(var i=0; i<this.items.length; i++) {
            products += "{";
            products += "'name'    : '" + this.items[i].info.brand + " " + this.items[i].info.title + "',";
            products += "'id'    : '" + this.items[i].info.sku + "',";
            products += "'price'    : '" + this.items[i].info.price + "',";
            products += "'brand'    : '" + this.items[i].info.brand + "',";
            products += "'category'    : '" + this.items[i].info.category + "',";
            products += "'variant'    : '" + this.items[i].info.color + "',";
            products += "'quantity'    : '" + this.items[i].quantity + "',";
            products += "}";
            if(i != (this.items.length - 1)){
                products += ',';
            }
            console.log(products);
        }

So when I print the products, you can see the entire products section is within double quotes. What I am trying to do is there should be no double quote before the opening bracket of the first product, and after the last bracket of the last product.

You probably are trying to build an object, in which case you should just use .map on this.items , eg:

 function example() { return { products: this.items.map((item) => { return { "name": item.info.brand + " " + item.info.title, "id": item.info.sku, "price": item.info.price, "brand": item.info.brand, "category": item.info.category, "variant": item.info.color, "quantity": item.info.quantity }; })}; } console.log( example.bind({ items: [{info: { brand: "whirlpool", title: "dishwasher", sku: "123", price: "$140", category: "dishwashers", color: "white", quantity: 2}}]})() )
