NodeJS' url module of course doesn't include __proto__ when enlisting parameters (in /?__proto__=hi for example).
People using objects as maps are insane. They are so insane, that they don't even realise that.

So here the function that does same thing as new operator in javascript:
// we define our function Person that assigns properties to THIS that points to some object
const Person = function(name, lastName) {
this.name = name;
this.lastName = lastName;
}

// in Person prototype property we define our functions
Person.prototype.getName = function() {
return this.name;
}

Person.prototype.getLastName = function() {
return this.lastName;
}

// function that simulates new operator
// first argument is a function that would act as constructor
// second argument is an arguments that would be passed to constructor
function New(func, ...args) {
// with Object.create() we create a new object and assign [[__proto__]] from "func" prototype property
let object = Object.create(func.prototype);
// here we're calling "func" with THIS pointing to object
func.apply(object, args);
// then we return it
return object;
}

let person = New(Person, "Name", "LastName");
console.dir(person);

// so this is how prototype OOP works in javascript
