Name

SyntaxError — thrown to signal a syntax error

Inherits from

Object → Error → SyntaxError

Constructor

new SyntaxError()
new SyntaxError(message)

Arguments

message

An optional error message that provides details about the exception. If specified, this argument is used as the value for the message property of the SyntaxError object.

Returns

A newly constructed SyntaxError 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 SyntaxError() 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. See Error.message for details.

name

A string that specifies the type of the exception. All SyntaxError objects inherit the value “SyntaxError” for this property.

Description

An instance of the SyntaxError class is thrown to signal a syntax error in JavaScript code. The eval() method, the Function() constructor, and the RegExp() constructor may all throw exceptions of this type. See Error for details about throwing and catching exceptions.
