}

//in this case if some other equal config was used to instance the same class, that will be the same instance class

const privateKey: string = JSON.stringfy(myClassConfig);
const total = 10;
const myClassInstance1: MyClassThatIWannaToBeUnique =
Singleton.getInstance<MyClassThatIWannaToBeUnique>(
privateKey,
MyClassThatIWannaToBeUnique,
"test",
total
);
const myClassInstance2: MyClassThatIWannaToBeUnique =
Singleton.getInstance<MyClassThatIWannaToBeUnique>(
privateKey,
MyClassThatIWannaToBeUnique,
"test",
total
);
//to prove that be the same instance, I will change a name of instance 1
myClassInstance1.name = "There is no test anymore";
console.log(myClassInstance1.name === myClassInstance2.name, "same name and same memory location");

```
