In this tutorial I’ve noticed a strange way to check for isEmpty:
statements like:

   if (this.firstName && this.lastName)       
                             or
  return this.firstName && this.lastName && this.email &&this.purchaseAgreementSigned;

Are those statements checking for isEmpty?

Was going to ask the same thing. I think returning something rather than nothing is also returning an implicit boolean value.

this answer seems to confirm that. An if statement without a conditional statement can be used to check for emptiness.

Similar question, and also wondering why my solution was considered incorrect, I typed:

if (this.firstName && this.lastName this.lastName && this.email && this.purchaseAgreementSigned ){
return true;
};

Does it not ammount to the same thing?

It seems to me that the method with the submitForm function was forgotten in the exercise.
If you don’t see any difference when clicking on the button, check if you have any method for submit
e.g.

submitForm: function(){
      console.log('Form is submitted!')
    }
