Question

What gets printed?
var i=6;
while(i<9)
{
i++;
document.write("i value is"+i+"
");
}

I understand that the result is a loop of
"i value is ____"
"i value is ____"
but I'm not sure what to put for i and how many times it's printed?

Answer 1

u have already declared value of i is 6 and the loop will continue until the value of i is less than 9

Answer 2

iteration 1:
i=6
while loop : (6<9) is TRUE
i= 7
i value is 7 is printed.

iteration 2:

while loop : (7<9) is TRUE
i= 8
i value is 8 is printed

iteration 3:
i=8
while loop : (8<9) is TRUE
i= 9
i value is 9 is printed

iteration 4:
i=9
while loop : (9<9) is FALSE
Control does no go inside, so nothing is printed.


so whats printed is
`i value is 7`
`i value is 8`
`i value is 9`

A great and fantastic thing about programming is that you check quite easily by compiling the code and executing it.
