Is there an opposite of catch?

Question

By running the following, you can run code if an error is thrown.

try {
    // test
} catch (e) {
    // error output
}

Is there a similar way to run code only if no error is thrown?

Answer 1

Sure there is, see the comment inline.

try {
// test
// No error is thrown if program control reaches here
} catch {
// error output
}

Consider using an additional try block in the "No error is thrown" part if you don't want the outer catch to handle any other errors.
