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
