+To update elements in an array based on specific conditions, you can pass a function as an argument.
+This function will act as a filter, It receives the old value and index, giving you flexibility to apply logic that targets specific cases.
+This might include using methods like `.startsWith()`, `includes()`, or other comparison techniques to determine which elements should be updated.
 
 ```jsx
+// update users with username that starts with "t"
 setStore("users", (user) => user.username.startsWith("t"), "loggedIn", false)
-```
 
-In addition to [`.startsWith`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/startsWith), you can use other array methods like [`.find`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find) to filter for the values that you need.
+// update users with location "Canada"
+setStore("users", (user) => user.location == "Canada" , "loggedIn", false)
+
+// update users with id 1, 2 or 3 
+let ids = [1,2,3] 
+setStore("users", (user) => ids.includes(user.id) , "loggedIn", false)
+```
