idea of strict class template like C++

myClass.js

'use strict'
/*================ Requires =====================================*/
//let utils = require( './utils'   );

/*================ Class Variables/Constants ====================*/
let methods ; // Mandatory
const  CODE_STRING = '<<code>>';
let someClassVariable = 'someClassVariable';


/*======================== Exports  ========================*/
module.exports = MyClass;

/*======================== Class  ========================*/
function MyClass( args ) {
  if( !this )  return;

  // Private Variables
  let opts = 'opts';  // options
  let somePrivateVarable1 = 'somePrivateVarable1';

  // Public Variables
  let self = this; // Mandatory
  self.options = 'options';
  self.somePublicVariable1 = 'somePublicVariable1';

  // Private function/medhod
  // init();
  // parseAttrs();
   

  // Public Method
  MyClass.prototype.anyMethod1 =  anyMethod1InDifferentNameOfFunction;


  // Object Init
  console.log( "# Call init from MyClass" );
  init();

  // WorkFlow
  console.log( "# Call init from MyClass" );
  parseAttrs();

  /*=================== function  ===================*/
  function init () {
    // Any init function
    console.log( "=== init ===" );
  }

  function parseAttrs(){
    console.log( "=== This is parseAttrs ===" );
    console.log( "# Call anyMethod1InDifferentNameOfFunction from parseAttrs" );
    anyMethod1InDifferentNameOfFunction();
  }

  function anyMethod1InDifferentNameOfFunction(){
    console.log( "=== anyMethod1InDifferentNameOfFunction ===" );
    console.log('CODE_STRING = ' + CODE_STRING);
    console.log('someClassVariable = ' + someClassVariable);
    console.log('opts = ' + opts);
    console.log('somePrivateVarable1 = ' + somePrivateVarable1);
    console.log('self.options = ' + self.options);
    console.log('self.somePublicVariable1 = ' + self.somePublicVariable1);
  }
}

testMyClass.js

'use strict'
/*================ Requires =====================================*/
let MyClass = require( './myClass' );

console.log( "########### make myClass1" )
let myClass1 = new MyClass();
myClass1.somePublicVariable1 = 'somePublicVariable1 of myClass1';
console.log( myClass1.somePublicVariable1 );
myClass1.anyMethod1();


console.log( "########### make myClass2" )
let myClass2 = new MyClass();
myClass2.somePublicVariable1 = 'somePublicVariable1 of myClass2';
console.log( myClass2.somePublicVariable1 );
myClass2.anyMethod1();

try {
  myClass1.parseAttrs();
} catch(e) {
  console.log(e);
}
