Simen Bekkhus updated THRIFT-3916:
----------------------------------
    Description: 
In JavaScript, you can {{throw}} any object, including strings, but to get 
stack traces one should throw {{Errors}}.

The generated JS code throws the error string directly, instead of wrapping it 
in {{new Error}}.

Node core _only_ rejects with/throws Errors, never strings, and Thrift should 
follow the same standard.

https://nodejs.org/api/errors.html#errors_class_error

{quote}
All errors generated by Node.js, including all System and JavaScript errors, 
will either be instances of, or inherit from, the Error class.
