Fetch the Cart Id from the JSON response

Fetch the Cart Id from the JSON response

I am working on capturing the cartID in a JavaScript variable from a JSON response.

Here is the code I have so far that requests the cart information:

function getCart(url) {
   return fetch(url, {
       method: "GET",
       credentials: "same-origin"
   })
   .then(response => response.json())
};

var cartID = 'unknown';

getCart('/api/storefront/carts')
.then(data => console.log(JSON.stringify(data)))
.catch(error => console.error(error));

The data logged in the console looks like this:

Extract of full data:
[{"id":"c5f24d63-cd9a-46f2-be41-6ad31fc38b51","customerId":1,"email":"<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bdd0d8fddavalue="">[email protected]</a>", ................. }]

I've attempted different methods to capture the cart ID into the variable cartID, but it always shows as 'unknown' and is logged before the data response.

Do you have any suggestions on how to delay until the response is ready and then assign 'cartID' with the id value?

To extract the cartID from a JSON array response, you can utilize a loop to iterate over each cart object.

function fetchCartID(apiURL) {
    return fetch(apiURL, {
        method: 'GET',
        credentials: 'same-origin'
    })
    .then(response => response.json())
 };
 
 var cartIdentifier = 'unknown';
 
 fetchCartID('/api/storefront/carts')
 .then(
     data => {
         // The response consists of an array of cart objects. Extracting the ID from the first cart
         cartIdentifier = data[0].id;

         // Alternatively, looping through the response to extract the ID from each cart object
         for (var i = 0; i < data.length; i++) {
             cartIdentifier = data[i].id;
         }
     }
     )
 .catch(error => console.error(error));
