You can do like this,I hope it helps
let total = 0;
let JsonRes= "{
"cart": [
{
"id": 28,
"Name": "Retin a gel",
"Price": 50,
"Quantity": 3,
"Cost": 150,
"createdAt": "2019-03-15 02:44:55.047 +00:00",
"updatedAt": "2019-03-15 02:45:04.574 +00:00"
}
]
}"
for (let i = 0; i < JsonRes.cart.length(); i++) {
