Is it necessary to iterate the loop at only true condition? It looks like here in the while loop condition that "Dave is forcly trying to make the codition true to iterate the loop". Why don't just he wrote
do{
}while(correctGuess === false )
Isn't it give the same result?

Full Stack JavaScript Techdegree Student 11,638 PointsI can see both the method works.
But what i want to ask is , correctGuess has been set to false .
And as soon as , the randomNumber matches the guess , correctGuess is changed to true.
So isn't is easier to set the
while loop condition as
while(correctGuess === false )
because it will change only when the randomNumber matches guess and in that case it will exit the loop.
The only difference between mine and Dave code is that "I am iterating the loop at false value while Dave is iterating at true value of correctGuess.

Courses Plus Student 10,205 Pointserr I don't think I am understanding your question clearly enough.
To enter in a while loop, the condition must be true
I'll provide an example of what is occurring with both yours and Davids logic.
Let's say the answer is 1. But the user provides a 2
When using correctGuess === false, user repeats the loop
When using ! correctGuess , user repeats the loop
User now provides a 1
When using correctGuess === false, user exits the loop
When using ! correctGuess , user exits the loop

Most people I see, like to use the
