This assignment you will design two buttons $$Grade to Score Range$$ and $$Score to Grade$.$ Each button will trigger its corresponding function which prompts the user to provide input. Then each function will display what is shown in the table provided, based on the user$$s input. One of your functions will use a "JavaScript switch" statement, the other can use "JavaScript if$-$else$-$if$"$ statements. You are expected to handle invalid inputs and user errors properly.
