5,523 PointsQuestion was meant to say why can't I? Is one considered bad practice or both are fine?

35,170 PointsBecause the condition that while checks for must be a boolean, and since guess !== randomNumber will return a boolean value, you don't don't need to assign it to a variable.
That's why both work
// Okay
while(guess !== randomNumber) {...}
// Also Okay
let whileCond = guess !== randomNumber;
while(whileCond) {...}
