How to solve the problem with the "module" pattern (JavaScript)?

Question

JavaScript

let Test = function() {
    let i = 0;
    return {
        inc() {
            i++;
        },
        cur() {
            return i;
        }
    };
};

let myTest1 = Test();

myTest1.inc();
console.log(myTest1.cur()); 
myTest1.inc();
console.log(myTest1.cur()); 
myTest1.inc();
console.log(myTest1.cur()); 

let myTest2 = Test();
myTest2.inc();
console.log(myTest2.cur()); 

//Вот этот способ не работает. Почему?
//Test().inc();
//Test().inc();
//Test().inc();
//console.log(Test().cur());

Well, obviously, in the first case, you create a variable and a place is allocated in memory for it and your "module" exists, so you can increment and print its value. In the second case, you simply call the method and that's it, the function is not stored anywhere in memory - it is simply collected by the garbage collector, because. There are no more links to it. (The first call creates a closure and saves it, the second call doesn't save the closure)
