Ans1:

<!DOCTYPE html>
<html>
<body>
<script>
   function isEqual() {
var x = 3;
var y = "3";
if(x==y){
alert("Equal");
}
else
alert("Not Equal");
}

function isIdentical() {
var x = 3;
var y = "3";
if(x===y){
alert("Identical");
}
else
alert("Not Identical");
}
</script>
<button type="submit" onclick="isEqual();">isEqual</button>
<button type="submit" onclick="isIdentical();">isIdentical</button>
</body>
</html>

var x=3 // implies assignment of integer 3 to variable x

var y= "3" implies assignment of string 3 to variable y

Hence difference can be identified by the double quotes.
