Question was meant to say why can't I? Is one considered bad practice or both are fine?

Because 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) {...}
