//Function Scope, with private value b, passed into func, as val;
var result = (function() {
	var b = (function(){
    	var secureValue = '5';

    }
  )();
  var res = b.method1;
  b = null; b = undefined; delete b; delete window.b; delete window["b"]; //delete shit
  return res;
})();
//then b=null, to set value as null, and b is undefined, to remove link between null and b.

console.log(result, 'и', result.toString());
