A static method is a method that belongs to a class rather than an instance of the class.
Static methods can be called without creating an instance of the class.
They are often used for utility functions that don't require any state.
Static methods cannot access non-static variables or methods.
Example: Math.max() is a static method that returns the maximum of two numbers.
To make a single instance application, use a mutex to ensure only one instance is running.
Create a named mutex when the application starts
Check if the mutex already exists, if it does, exit the application
Release the mutex when the application exits

Classes are used to create objects with shared properties and methods.
Modules can be imported and exported to be used in other files.
Classes can be extended and inherited to create new classes with additional properties
