Is it possible?

Hi guys, I don't understand the logic of the "do.. while loop". I mean.. Could it be possible to use this code?

'''javascript do { guess = prompt('I am thinking of a number between 1 and 10. What is it?'); guessCount +=1; } while ( ! parseInt(guess)===randomNumber) '''

Thanks for the answers! Luca

Here's some videos on loops https://teamtreehouse.com/library/feeling-loopy-with-java (The code is java but the syntax is very similar, and it explains the ideas very well).

// this is how do-while loops work.
do {
  // statement 1 will run at least 1 time (can be more if condition is true)
  // statement 2 will run at least 1 time (can be more if condition is true)
} while( condition );  // keep doing statements 1 & 2 when the while condition is true. stop when condition is false

Could it be possible to use this code?

Yes, you can use that code. But you need to declare and initialize "guessCount" and "randomNumber"
