Is this wrong?

Complete the code below to create a for loop that executes 10 times, writing the value of the variable i to the document each time:

for (var i = 0; i < 11; i ++) { document.write(i); }

and this code will print 10 times, right?

So, Mr. William you saying;

for (var i = 0; i => 10; i ++) { document.write(i); }

now will print 10 times?

No. remember the loop will STOP executing when the termination condition is false,

for (var i = 0; i >= 10; i ++) { document.write(i); }

initial value of i is 0, this automatically makes its loop termination condition i>=10 false. Thus by writing it this way, it will print ZERO time, as the loop won't be executed at all.
