Hello. How to set something like a constructor inside a function, which will be invariably called when creating an object (there must be a certain sequence of actions and initialization of one variable in the constructor):

var clazz = new myFunction(op);

It is desirable that it be inside the function:

 function myFunction(op) { constructor(){ ... ... ... ... } }

Ps. Without the use of libraries.

    That is, in this case, myFunction is not a constructor, yes? - user3521

myFunction and is a constructor.

 function myFunction(op) { this.var1 = ''; //... }

PS If you want a constructor function EXACTLY that will be called, then ...

  function myFunction(op) { this.__constructor = function(){ this.var1 = ''; } //БИНГО: this.__constructor(); //... }
