Front End Web Development Techdegree Student 7,117 Pointslooping with while
in the video does the code mean if the final outcome of the random number is 10 it stops? because that will mean 10 < 10 which is false and so does it mean the loop will stop? i dont really understand this. Can someone help me?

As Guil explained in the video, the length of the loop depends solely on the counter variable. If you want to go through the loop 10 times, you write counter < 10, if you want to go through 100 times, you write counter < 100.
This kind of while loop is essentially a for loop, where the iterator is called counter in this case. As a for loop it would look something like this:
for(let counter = 0; counter < 10; counter++){
console.log(`The random number is: ${getRandomNumber(10)}`);
}
As i said before, the number of iterations depends solely on the counter variable's value, since that is in the while loop's condition. See:
while(counter < 10)
If we wanted to end the loop when our randomNumberGenerator gets 10, we should do something like this:
while(getRandomNumber(10) !== 10){
//Do stuff
}
I hope it helps, if you have any questions feel free to ask!

Courses Plus Student 987 PointsThe main point here is counter variable starts at '0', not at '1'. If you start the counter variable at '1', you can write 'while (counter <= 10)' then it will loop 10 times too.
