Name
Error: a generic exception â ECMAScript v3: Object â Error
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 uses it as the value of its message
property; otherwise, it uses 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. The name
property specifies the type of the

property can provide human-readable details about the
