How to represent Get error type using a switch statement?

Question

How to represent the following using a switch statement?

if (e instanceof EvalError) {
    console.log(e.name + ': ' + e.message);
  } else if (e instanceof RangeError) {
    console.log(e.name + ': ' + e.message);
  }

While switch is using strict comparison, you could take true as expression and the other test as value for testing.

switch (true) {
    case e instanceof EvalError:
        console.log(e.name + ': ' + e.message);
        break;
    case e instanceof RangeError:
        console.log(e.name + ': ' + e.message);
        break;
}
