Better error messages

• Update error messages

Type predicate

• All validation functions now accept unknown type and perform internal type checking
• All validation functions now return a type predicate (e.g., v is string) instead of a boolean. Except for isFalsy() and isTruthy() still return boolean values.
• All contain functions remain unchanged and continue to return boolean values.
• All normalize functions remain unchanged and continue to return string | false
• For both isValidDate() and isValidTimestamp(), min and max parameters can be of type date or timestamp.
• Improved isDate() function to return false when date = date.setDate(NaN)
• Improved isEmail() function to return false when Top-Level Domain starts with a number
• Improved isValidTimestamp() function to have better min and max conversions
• Improved test suite to more than 3200 tests with enhanced accuracy and edge case coverage

Improve throwError for compare function

• compare() function now throws an error when a comparison fails and throwError is true, for both unary and binary comparators

throwErr

• Functions have a throwErr property to throw specific error instead of false
• isBase64 regex now rejects empty strings, improving validation and error handling

Delete b64Encode() and b64Decode()

• Delete b64Encode() and b64Decode() functions

String, number and validNumber support for undefined and null in Typescript

• String, number and validNumber functions support undefined and null values in Typescript

Better isProperty() typings

• Update isProperty() function inputs typings

number functions handles string as input

• Update number validation functions type for string as input

string functions empty string cases

• Update string validation functions for empty string cases

Base64 transform

• Add b64Encode() and b64Decode() methods to transform strings accordingly.
