Javascript create object in function style

#1 (object) 
function Person(f){
      this.firstname = f;

      alert(this.firstname);
    }
    var me = new Person('benny');


#2 (function) 
    function Person(f){
       alert(f);
    }
    Person('benny');

Im new in js oop, I have knowledge of oop in PHP

My question is what's different between 1st one and 2nd one?

in php, if I create an obj, i will start with class{}

in JS, it seems like you can also create an obj var obj = {} OR like create it like a function?

can someone enplane how it works?

The first is a constructor function and the second is just a plain function with a capital letter.

The constructor function is a way of creating data types. JavaScript offers prototypal inheritance. 

Person.prototype.newmethod = function(){...};

There is a class keyword in the new JavaScript version. You could use also TypeScript. It may make more sense to you.
