Basic Javascript help

I can’t figure out why this doesn’t work, thanks for any help.

Your code so far

function trueOrFalse(wasThatTrue) {
// Only change code below this line

if (wasThatTrue = true) {
return "Yes, that was true";
if (wasThatTrue = false) {
return "No, that was false";
// Only change code above this line

var pig = trueOrFalse (false);
console.log (pig);

Challenge: Use Conditional Logic with If Statements

Link to the challenge:

remember the difference between assignment operator and comparison operator

Check this link i am sure you will figure out

Thanks for your replies but it didn’t help me.
Line 3 prints to the console that the variable wasThatTrue = false
but the function still evaluates wasThatTrue as being equal to true.
I just can’t see why.

Oh I didn’t know about ==. I thought it mean “is not equal to”…
They tell you that in the following lesson!

You have met = assignment operator, and === is the comparison operator

They do different things

But this challenge was just teaching you that if you put the true boolean inside the parenthesis the if statement will execute, and if you put the false boolean, it will not execute
if you assign something to a variable you are overwriting a variable

look at the example code. It is that simple. You just needed to do the same thing with stuff named in a different way.
