Memoize not working properly with objects and custom comparator

[ohoho7]

Comparing objects with custom comparator not working properly, example:

function nestedXtoString(myObj) {
    return myObj.x.toString();
}
const memoizedNestedXtoString = memoize(nestedXtoString, ([prev], [curr]) => {
    console.log("compared", prev, curr);
    return prev.x === curr.x;
});
const myObj = {x: 55};

console.log(memoizedNestedXtoString(myObj)); // "55"
myObj.x = 7;
console.log(myObj); // {x: 7}
console.log(memoizedNestedXtoString(myObj)); // 55

Comparator gives log:

compared {x: 7} {x: 7}

@ohoho7 Everything is working as expected. Your comparator function will be called each time you call memoized function, no matter if the passed argument is referentially equal.
