InternalError

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The InternalError object indicates an error that occurred internally in the JavaScript engine. For example: "InternalError: too much recursion".

Syntax

new InternalError([message[, fileName[, lineNumber]]])

Parameters

message
Optional. Human-readable description of the error
fileName
Optional. The name of the file containing the code that caused the exception
lineNumber
Optional. The line number of the code that caused the exception

Description

An InternalError is thrown whenever an internal error in the JavaScript engine occurred.

Example cases are mostly when something is too large, e.g.:

  • "too many switch cases",
  • "too many parentheses in regular expression",
  • "array initializer too large",
  • "too much recursion".

Properties
