Reference Address little Exercise

var student=function() {}; var bosn=New  Student (); student.prototype.x= ' 101 '; Student.prototype={y:2};console.log (bosn.x)

Today on the Internet to see the above example, that Console.log (bosn.x) value of UNDEFINED,BOSN.Y value is 2, in fact, the answer is bosn.x 101,bosn.y for undefined, for the reasons see:

In addition, in C #, String a = "AAAA";

B=a;

A= "BBB";

The value of output B is still "AAAA", the reason is not the same as this, C # string is a reference pass, but the value is passed like a copy, so the value will not change, but the principle is different (heard, not personally confirmed)
