let discount_code="";
function getDiscountCode() {

    .then((val) => val || "")
    .catch((error) => "");
}
function printLocalStorage(){
    getDiscountCode().then((discount_code) => {
    console.log("discount_code",discount_code)
     document.getElementById("disc").innerText=discount_code;
      VajroSDK.actions.showAlert({
                    title: "Discount Applied",
                    message: `Shopping for: ${discount_code}`
            });
            VajroSDK.actions.applyDiscount([discount_code]);
    });
}
printLocalStorage();

<div id="disc">the discount code is </div>

Best Practices

Check for null: Always verify that res.value exists before using it.
Keep keys consistent: Use the same naming conventions as in setLocalStorage.
Use for personalization: Great for restoring last-viewed product or theme preference.
Combine with fallbacks: If value is missing, load defaults gracefully.
Cache efficiently: Retrieve only what’s needed for optimal performance.

Caveats

Missing key: Returns null if the specified key doesn’t exist.
Device-local only: Data is stored per device — not synced between users or sessions.
Not encrypted: Only use for non-sensitive data.
Async behavior: Always handle Promises to avoid silent errors.
Limited scope: Works exclusively inside the Superfans app environment.
