+To retrieve a specific user trait using the analytics.js get method, you can access the trait by invoking `analytics.user().traits().firstName`. This will return the firstName trait of the user.
+
+Similarly, to retrieve a specific group trait, you can use the method `analytics.group().traits().companyName`. This will return the companyName trait of the group.
+
+When accessing specific traits stored in the browser's localStorage, you'll need to utilize the [JSON.parse()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse) method due to the fact that the stored data is typically in string format.

 ## Storage Priority
 
 By default, Analytics.js uses `localStorage` as its preferred storage location, with Cookies as a fallback when `localStorage` is not available or not populated. An in-memory storage is used as a last fallback if all the previous ones are disabled.
