Welcome to Day 18 of our 21 Days of Problem Solving with JavaScript challenge! 🚀
After understanding the basics of recursion, today we apply it to Arrays and Strings — the most common data structures you’ll work with in real-world problems.

You’ll learn:
✅ How to traverse arrays using recursion
✅ How to process strings character by character recursively
✅ How to solve classic array and string problems using recursion
✅ How recursion replaces loops in certain scenarios
✅ How base cases and recursive calls work together
This session will help you think recursively and write cleaner, more elegant solutions for problems involving sequences and text 💪
