Question

Given the following JavaScript code, what will be displayed on the web page?

var i, j;

for (i=1; i<=3; i++)

{

     for (j=2; j<=5; j++)

     {

           document.write(i+ "," + j + "; ");

     }

     document.write("<br>");

}

2,3;
3,4;
4,5;
4,6;

Answer 1

OUTPUT:

EXPLANATION:

i	j	Output
1	2 3 4 5	1,2;1,3;1,4;1,5;
2	2 3 4 5	2,2;2,3;2,4;2,5;
3	2 3 4 5	3,2;3,3;3,4;3,5;

For each value of i=1,2,3 inner loop will go through values j=2,3,4,5 and so i,j are printed. After each iteration of i, there is <br> so after each iteration of i, line has been changed.
