 // Predict and explain first BEFORE you run any code...
 
 // this function should square any number but instead we're going to get an error
 
 // I think this code will throw an error because we are passing an actual number into the parameters but javascript only allows a variable to be passed into the parameters that can be used to store information so i would need to change the number 3 into num ( and num here would act as the placeholder for any number passed in when the function gets called later) for this code to work because as it is i believe num would be undefined as it hasn't been defined anywhere.
