Constructor
new Error( )
new Error(message)Arguments
-
message An optional error message that provides details about the exception.
Returns
A newly constructed Error object. If the
message argument is specified, the Error
object will use it as the value of its message
property; otherwise, it will use an implementation-defined default
string as the value of that property. When the Error( ) constructor is called as a function, without the
new operator, it behaves just as it does when
called with the new operator.
Properties
-
message An error message that provides details about the exception. This property holds the string passed to the constructor or an implementation-defined default string.
-
name A string that specifies the type of the exception. For instances of the Error class and all of its subclasses, this property specifies the name of the constructor used to create the instance.
Methods
-
toString( ) Returns an implementation-defined string that represents this Error object.
Description
Instances of the Error class
represent errors or exceptions and are typically used with the
throw and try/catch statements.
