Singleton Design Pattern: Managing Global States in Your Applications

Depending on the language used sometimes you can even hide the type of the singleton instance in a function body (also assuming the PL support local static decls), so instead of having `TypeX.instance()` you can just have `xInstance()`.

Otherwise, the article does not mention the problem of race conditions but sometimes it might be better to use static constructors instead of performing lazy construction in the instance getter.

Have you ever found yourself dealing with an object that needs to be shared across multiple parts of your application—perhaps a database connection, a WebSocket client, or a configuration manager?

How do you manage such an object so that it remains consistent and accessible throughout the application or process lifecycle? This is where the Singleton Design Pattern comes into play.
