Error Objects


Error objects are created either by the environment (the browser) or by your code.

>>> var e = new Error('jaavcsritp is _not_ how you spell it');
>>> typeof e

"object"

Other than the Error constructor, six additional ones exist and they all inherit Error:

  • EvalError

  • RangeError

  • ReferenceError

  • SyntaxError

  • TypeError

  • URIError
