+Here's a simple JavaScript code snippet that creates a referral link that asks for a Bitcoin Lightning address:
+
+```javascript
+function createReferralLink() {
+  // Get the user's Bitcoin Lightning address
+  const lightningAddress = prompt("Please enter your Bitcoin Lightning address:");
+
+  // Construct the referral link
+  const referralLink = `https://example.com/referral?lightning_address=${encodeURIComponent(lightningAddress)}`;
+
+  // Return the referral link
+  return referralLink;
+}
+
+// Example usage
+const myReferralLink = createReferralLink();
+console.log("Your referral link:", myReferralLink);
+```
+
+In this code, the `createReferralLink()` function prompts the user to enter their Bitcoin Lightning address, and then constructs a referral link that includes the entered address as a query parameter. The `encodeURIComponent()` function is used to properly encode the Lightning address in the URL6.
+
+The resulting referral link can then be used to share with others, and when they click on it, the Lightning address will be passed along as a parameter.
+
+Please note that this is a basic example, and you may want to add additional functionality or error handling as needed for your specific use case.
