TypeError.prototype

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

Description

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

Properties

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

Methods

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