• First and Last Name Validations: Ensures names contain only alphabetical characters and conform to accepted standards.
• Username Validation: Validates usernames based on length, allowed characters, and restricted symbols.
• Email Validation: Ensures email addresses adhere to standard format and structure.
• Phone Number Validation: Validates phone numbers to match standard formats and character restrictions.
• Password Validation: Checks if input meets strong password criteria, such as minimum length and character variety.

• All validation functions return an object detailing if an error exists hasError and an associated errorMessage for intuitive error handling.

• Functions like checkBoolType() and checkStringType() offer runtime type verification to prevent unintended data types from causing errors in applications.

• With the VALID_MSG object, developers have a centralized repository of validation error messages, ensuring consistent feedback across the application.

• In-depth documentation ensures developers have all the information required to effectively leverage the library's capabilities
