    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.

    Summary

    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".
