I need to create a function named getFontSize(id) "done this part" . It wants me to create a variable named object that represents the object with a specified id value, then, return the font size of the text in that object. use the style object to retrieve the font size and ust the parseInt() function to extract the numeric value of the font size only. How do I do this
