3.11 Error Objects

ECMAScript v3 defines a


number
of classes that represent errors. The JavaScript interpreter
"throws" an object of one of these types when a runtime
error occurs. (See the throw and
try statements in Chapter 6 for
a discussion of throwing and catching errors.) Each error object has
a message
property that contains an implementation-specific error message. The
types of predefined error objects are Error, EvalError, RangeError,
ReferenceError, SyntaxError, TypeError, and URIError. You can find
out more about these classes in the core reference section of this
book.
