In the If at the end.Why do we not add correctGuess= true.?

In the If statement in the end why do we not do it like this: if (correctGuess= true) { document.write("<h1> You Guessed the number right.</h1>"); document.write("It took you " + guessCount + " tries to guess the correct number " + randomNumber + "."); } else if (correctGuess= false){ document.write("<h1> Sorry. You did not guess the number.</h1>") }

Check your code and check IF statment 

=   is for Asign value to 
Example : 
var a = 2;

== is for equal check :)

var a == 2      -> this return true or false

so you cant do this

 if (correctGuess= true)

Here is another way of doing it:

EDIT: if you just need to check if a variable is true or truthy, then you don't really need to say == true, == false etc..

if (correctGuess) { // same as saying "correctGuess == true"
  // do something
} else if (!correctGuess) { // same as saying "correctGuess != true"
  // do something
} else {
  // do something
}

So if I add:

if (correctGuess === true).

Would that be right.?

I think I am confused about the same thing, I am wondering why when you call the if (correctGuess) later in the code why is that not equivalent to correctGuess = false; at the top? I was under the impression that the only way to call 'correctGuess = true' is either typing it out like that or '(! correctGuess)'... can anyone help explain this??
