 Explanation:

-- The first reference of browser is an assignment, an emoji 📝 indicates the value is changed in this line. In many
+- The topmost entry in the floating window indicates there are 3 references for the symbol <span style="color:red"> _browser_ </span> within closure.js
+- The first reference of browser is an assignment, an emoji 📝 indicates the value is modified in this line. In many
   cases, we search for references to find out when the value changed.
 - The second reference of `browser` is inside function `displayName` and `displayName` sit inside `makeFunc`, So you
   will see `displayName{} <- makeFunc{}`
-- The third similar to the second, as var browser is on the right side of '=', the value not changed in this line
-  and emoji is not shown.
+- The next occurrence of `browser` is located within the function `displayName`, which is nested inside `makeFunc`. Hence, the display reads `displayName{} <- makeFunc{}.`
+- The final reference is akin to the previous one, except that since `browser` appears on the right side of the `=`, its value remains unaltered, and consequently, no emoji is displayed.

 You may find a 🦕 dinosaur(d) on the line of `Rectangle rect,` which means there is a definition (d for def) of rect in this line.
 
 `<- f main()` means the definition is inside function main().
