SyntaxError.prototype

The SyntaxError.prototype property represents the prototype for the SyntaxError constructor.

Description

All SyntaxError instances inherit from SyntaxError.prototype. You can use the prototype to add properties or methods to all instances.

Properties

SyntaxError.prototype.constructor: Specifies the function that created an instance's prototype.
SyntaxError.prototype.message: Error message. Although ECMA-262 specifies that SyntaxError should provide its own message property, in SpiderMonkey, it inherits Error.prototype.message.
SyntaxError.prototype.name: Error name. Inherited from Error.
SyntaxError.prototype.fileName: Path to file that raised this error. Inherited from Error.
SyntaxError.prototype.lineNumber: Line number in file that raised this error. Inherited from Error.
SyntaxError.prototype.columnNumber: Column number in line that raised this error. Inherited from Error.
SyntaxError.prototype.stack: Stack trace. Inherited from Error.

Methods

Although the SyntaxError prototype object does not contain any methods of its own, SyntaxError instances do inherit some methods through the prototype chain.
