I not able to find the error in this code

Tell us what’s happening:

Your code so far

// Example
function ourTrueOrFalse(isItTrue) {
  if (isItTrue) { 
    return "Yes, it's true";
  }
  return "No, it's false";
}

// Setup
function trueOrFalse(wasThatTrue) {

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

}

// Change this value to test
trueOrFalse(true);
