Errors#

Applications running in Node.js will generally experience four categories of errors:

• Standard JavaScript errors such as:
  • <EvalError> : thrown when a call to eval() fails.
  • <SyntaxError> : thrown in response to improper JavaScript language syntax.
  • <RangeError> : thrown when a value is not within an expected range
  • <ReferenceError> : thrown when using undefined variables
