Why doesn't instanceof work on instances of Error subclasses under babel-node?

Question

I am seeing that the instanceof operator doesn\'t work on instances of Error subclasses, when running under babel-node version 6.1.18/Node version

Answer 1

instanceof will not work for subclassed errors if the compile target is set to "es5". I set the target to "es6" in my tsconfig.json and instanceof produced the right result.
