+### Exercise 3: String Array Processing
+Create an array of your favorite movies/books/songs and practice different loop types.
+
+**Requirements:**
+- Create an array with at least 5 string values
+- Use a traditional `for` loop to display items with numbers (1. Item Name)
+- Use a `for...of` loop to display items in uppercase
+- Use `forEach()` method to count and display the total characters
+
+**Example Output:**
+```
+Traditional for loop:
+1. The Matrix
+2. Inception
+3. Interstellar
+
+For...of loop (uppercase):
+THE MATRIX
+INCEPTION
+INTERSTELLAR
+
+Character count:
+Total characters across all titles: 42
