Declare array of objects

Question

I need to store array of objects and then convert that into string using JSON.stringify and transfer that string to external link. Below is my typescript code..

 

let orderItems: any[] = [];

let order_data = {};

 

this.storage.get("cart").then((cart) => {

   cart.forEach((element, index) => {

         orderItems.push({ "product_id": element.product.id, "quantity": element.qty });

         });

   });

console.log(orderItems);

order_data = {

"customer_name": "Singh",

"line_items": orderItems,

}

console.log(JSON.stringify(order_data));

 

 In my console I got empty array of objects.....   {"customer_name":"Singh","line_items":[]}

 

Anyone here pls help me out of this... Thank you in advance....
