If we don't have a value for a variable in the very beginning, we can create it without assigning anything to it. We do, however, have to set its type.

Spot on! myDouble is now declared and set to hold double-type values.

Psst: have you noticed how every line we wrote so far ended with a semicolon? That's how we mark the end of a statement.

Does that really create myDouble as a double-type variable?
