Explain the output

Question

var x=new String ("hello");
var y=new String ("hello");
if(x===y) {alert("a"); }
else if (x==y) {alert("b"); }

Why is it alerting b? Ain't x & y identical/equivalent ?

Answer 1

I tried
var x = new String("hello");
var y = new String("hello");

if(x.localeCompare(y)==0)
alert("a");

else if(x.localeCompare(y) == 0)
alert("b");

and it works fine
But when I ran your code, it doesn't alert anything, because when two string objects are compared using '==' operator JS returns false
