      FAQ: Why does the semicolon drop in Robotics when I toggle between languages?

      It is best practice to have a semicolon at the end of JavaScript. The semicolon will be removed when toggling between the languages. Therefore, the autograder will allow you to pass whether or not that semicolon is there or not.
