Find the Invalid Switch Expression 🧐¶

Did you know?

One of the four snippets below is invalid (won’t compile).

Can you guess which one and why?

According to the language specification, you can’t begin a switch expression at the beginning of a line.

To solve this:

• assign the expression to a variable (option 2)
• wrap the expression with parenthesis (option 3)
• return the expression (option 4)
