What is the Singleton Pattern in TypeScript?

Can you explain the Singleton Pattern in TypeScript?

Sure! The Singleton Pattern ensures a class has only one instance and provides a global point of access to it.

How do I implement the Singleton Pattern in TypeScript?

You can implement it by creating a class with a private constructor and a static method to get the instance.

Can you show me a code example?

Absolutely! Here's a simple example:

class Singleton {
    private static instance: Singleton;

    private constructor() {}

    public static getInstance(): Singleton {
        if (!Singleton.instance) {
            Singleton.instance = new Singleton();
        }
        return Singleton.instance;
    }
}

This ensures that only one instance of Singleton can exist.

What are the benefits of using the Singleton Pattern?

The main benefits include controlled access to a single instance, reduced memory usage, and easier debugging.
