Password Strength Indicator

Objective: Implement a function that evaluates the strength of a password based on certain criteria and returns a strength score or label.

Instructions:

1. Create a function called checkPasswordStrength that takes a password as input.
2. The function should evaluate the password based on the following criteria:
   • Length of the password.
   • Inclusion of uppercase and lowercase letters.
   • Inclusion of numbers.
   • Inclusion of special characters (e.g., !@#$%^&*).
3. The function should return a score or label such as "Weak", "Medium", or "Strong".

Example Usage:

console.log(checkPasswordStrength('Password123'));  // Output: "Medium"
console.log(checkPasswordStrength('Password@123'));  // Output: "Strong"
console.log(checkPasswordStrength('pass'));  // Output: "Weak"

Requirements:

• The function should check for a combination of length, character variety (uppercase, lowercase, numbers, special characters).
• Return a label or score to indicate the password strength.

Hints:

1. Use regular expressions to check for the presence of numbers, uppercase letters, and special characters.
2. Create a point system based on the criteria and return the label based on the score.

Bonus:

1. Provide suggestions to improve a weak password (e.g., "Add special characters").
2. Allow customization of strength rules (e.g., minimum length, required character types).
