Error Name          Description

EvalError           An error in the eval() function has occurred.

RangeError          Out of range number value has occurred.

ReferenceError      An illegal reference has occurred.

SyntaxError         A syntax error within code inside the eval() function has occurred.
                    All other syntax errors are not caught by try/catch/finally, and will
                    trigger the default browser error message associated with the error. 
                    To catch actual syntax errors, you may use the onerror event.

TypeError           An error in the expected variable type has occurred.

URIError            An error when encoding or decoding the URI has occurred 
                   (ie: when calling encodeURI()).
