How can you re-throw an error caught within a `catch` block after logging it?

To re-throw an error after logging it, simply use the `throw` keyword without any arguments inside the `catch` block. This will propagate the error up the call stack to the next available error handler. Example: `catch (error) { console.error('Error:', error); throw error; }`. This is important if the current function cannot fully resolve the error and needs to signal it to its caller.
