// ES6 classes

public // - access anywhere
private // - access only inside class ( without inheritance )
protected // - access only inside class and its children

readonly - // can be assigned only on default/constructor stages
static - // common property for all class instances ( as if we write it to class prototype )

abstract // - can be used only for inheritance, putting before method make method obligatory to implement ( for children )
