hi Serzh Ivasyshyn, 

I am not sure about Tizen support with ECMAScript6 or not. 
Here is the table => https://kangax.github.io/compat-table/es6/

If not support, you can not use 'class' in 'JavaScript'. 

But you can still use object oriented programming in JS. 

 // Define a class like this
    function Person(name, gender){
       // Add object properties like this
       this.name = name;
       this.gender = gender;
    }

    // Add methods like this.  All Person objects will be able to invoke this
    Person.prototype.speak = function(){
        alert("Howdy, my name is" + this.name);
    };

    // Instantiate new objects with 'new'
    var person = new Person("Bob", "M");

    // Invoke methods like this
    person.speak(); // alerts "Howdy, my name is Bob"
