I didn't get all for loops in Javascript

Question

/* If 'i' has to less than or equal 5.
Why the outputs is 6? */
for (i=1; i<=5; i++) {}
document.write(i + "<br />");// outputs 6

/* If 'i' has to less than 5.
Why the outputs is 5? */
for (i=1; i<5; i++) {}
document.write(i + "<br />");// outputs 5

/*
I know that document.write is not in the
code block but, I still do not understand
the because of these outputs.
sorry if my English is bad.
*/

Answer 1

In the first part

The for loop code block runs at i = 1, 2, 3....5 and then stops at i = 6 (When i <= 5 is false)

So the next line after the for loop code block captures i at 6.

In the second part,

The for loop code block runs at i = 1, 2,... 4, and stops at i = 5 (when i < 5 is false)
So the next line after the for loop code block captures i at 5.

Thanks Gordon I get it the logic now
