Why not the function declaration form?

There were no other functions defined in the file, so I did function expressions because it is what I tend to use. There is precedence for function expressions in test/parallel files. test-http-parser.js has 21 function expressions. Still, it was basically an arbitrary decision on my part and I can switch them to function declarations in this file if you or anyone else has a strong preference.

process.stdout.end();
} catch (e) {
exceptionCaught = true;
assert.ok(common.isError(e));
assert.equal('process.stdout cannot be closed.', e.message);
}
};

const validateError = function(e) {
return e instanceof Error &&
e.message === 'process.stdout cannot be closed.';
};

assert.ok(exceptionCaught);
assert.throws(shouldThrow, validateError);
