    Hello. Well done on your solution! Check the mobile view - the rounded corners are missing though.

    I would avoid variable hoisting as it can introduce unintuitive bugs. Your code snippet should print undefined - the variable was declared but not assigned. The switch statement is an alternative to if/else. Personally I would only use switch statements when I need to make simple assignments, usually one liners. In some languages, there are claims that switch statements are quicker to execute but I have rarely seen that in practice and normally see them as a style preference.
