- message: String
An error message that provides details about the exception.
- name: String
The name of the error based on the constructor used.
- stack: String
The script stack trace.
This property is filled on throwing or via an explicit call captureStackTrace(Error, Function).
- Error()
Constructs the Error object.
- Error(msg: String)
Constructs the Error object using the specified message.
Parameters:
- msg - the message to use,.
- static captureStackTrace(error: Error, constructorOpt: Function): void
Fills the stack property for the passed error.
The optional constructorOpt parameter allows you to pass in a function value. When collecting the stack trace all frames above the topmost call to this function, including that call, are left out of the stack trace. This can be useful to hide implementation details that won’t be useful to the user. The usual way of defining a custom error that captures a stack trace would be:
Parameters:
- error - The error whose stack trace should be filled.
- constructorOpt - An optional filter to hide the topmost stack frames.
