🎯 High-Low Number Guessing Game — Alert and Prompt Edition (29-Stu_HighLow)

Work with a partner to create an interactive number guessing game using only JavaScript’s built-in alert, prompt, and confirm functions.

👤 User Story

As a player,
I want to guess a hidden number between 1 and 100,
so that I can test my logic and get immediate feedback.

---

✅ Acceptance Criteria

• It’s done when a random number between 1 and 100 is generated each game.
• It’s done when the player enters a guess using window.prompt().
• It’s done when the game tells the player if their guess is too high, too low, or correct.
• It’s done when the game tracks the number of guesses made.
• It’s done when the game congratulates the player when they win.
• It’s done when the player can choose to play again with window.confirm().

🧱 Your Task

1. Create a function called playHighLowGame().
2. Inside the function:
   • Generate a random number between 1 and 100.
   • Keep track of the number of attempts.
   • Use a loop to repeatedly ask for guesses with prompt().
   • Validate that the guess is a number between 1 and 100.
   • Display feedback using alert() for each guess:
     • “Too high!”
     • “Too low!”
     • “Correct!”
   • End the loop when the correct number is guessed or the user cancels.
   • Ask if they want to play again using confirm().

💡 Hints

• Use Math.random() and Math.floor() to generate a number between 1 and 100.
• Convert string input to a number with parseInt().
• Use isNaN() to handle invalid inputs.
• Use recursion (call playHighLowGame() again) to restart.
• Make sure to return or break to stop loops correctly.

---

🧠 Bonus Challenges

• Limit the number of attempts (e.g., 10 tries maximum).
• Give hints like “🔥 Very close!” when the guess is within 5 of the number.
• Track best scores or total games played.
• Use emojis or fun phrasing to make feedback more engaging.
