I'm having trouble understanding the theory of the do while loops. Could someone explain what's happening in each step?

Here's one of the quiz questions. Let's take a look at it and go through it... slowly

var x = 0;
do {
  console.log('I love JavaScript');
  x += 1; 
} while ( x <= 3)

Ok so we start with x set to 0. Agreed? Now no matter what, this loop will always run at least once. So it does the console.log which prints I love Javascript to the console. That has now been printed a total of one time. It then increments x by one which makes x equal to 1. Is x less than or equal to three? Yes! So we do it again.

Now x is equal to 1 and we print I love JavaScript again bringing our prints to a total of 2. Then we increment x again making x equal to 2. Is 2 less than or equal to three? Yes! Do it again.

Now x is 2. We print our message again for a total of 3 prints to the console. Now we increment x to 3. Is 3 less than or equal to 3? Yes!

Now x is 3. We print our message again for a total of 4 prints to the console. Now we increment x to 4. Is 4 less than or equal to 3? No! Our do while loop exits.

Now the question asks you to fill in the number if you want to print 10 times. If we had a total of 4 prints when x is less than or equal to 3... what should x be less than or equal to if we want it to print 10 times? One less than the number we want to print out. Hope this helps!
