Answer 1

Thanks for your response.

Answer 2

thats because the second while loop is exactly the same, but it is only printed after the while loop has finished
function(){
while(){}
}
document.write();
^this should be inside the while loop to output the same as the first one

Answer 3

no problem

Answer 4

The two codes shows different results as
in the 1st code the [ document.write(); ] is inside the while loop so it will print the output of each iteration of the while loop....
but in the 2nd code the [ document.write(); ] is outside the while loop so it will print the final output of the while loop....
i hope you understand it..!!
to make it the same output place the [ document.write(); ] of the 2nd code inside the while loop, like this:
[
//First code
document.write("First Code<br/>");
var x=0;
while(x<4){
document.write(x+ "<br/>");
x++;
}
document.write("<hr/>Second Code<br/>");

//Second code
var y=0;
while(y<4) {
document.write(y+ "</br>");
y++;
}
//document.write(y);
]
