+
+//reasons for the changes:
+
+// 1. Unreachable Code: The console.log(greetingStr); 
+// inside the function occurs after the return statement. 
+// Once a function hits a return, it immediately exits, 
+// making anything below it completely unreachable.
+
+// 2. Redundant Code: The variable const greetingStr = greeting + ", " + name + "!"; 
+// was created using old string concatenation, but the function actually returns a template literal expression (${greeting}, ${name}!). 
+// Since greetingStr is never used elsewhere, it can be deleted entirely.
+
+// 3. Unused Global Variable: let testName = "Jerry"; is declared but immediately overwritten by testName = "Aman"; 
+// before ever being used, making the initial assignment redundant.
