What is the use of Break, when you are increment the value of guessCount?

As in the second example, David gives the parameter to the while as guessCount < 10. and also use the break keyword to end the while loop.

David, when you are adding the guessCount with 1, then why did you use break keyword, without "break" also it may end, right? Please correct me if I missed anything?

Dave explains this in the video.

He says, "Now the loop will either run ten times, or if the user guesses the correct number first, the loop ends because of the break statement."

So without the break it would still eventually end, but even if you guessed the right number along the way it would keep asking for more numbers until you entered 10 of them.
