However, even if a deterministic algorithm is used, the value can vary across processes. The following code shows an example: C# Copy ...

Error.prototype.lineNumber Line number in file that raised this error. The following code is an example. A high quality implementation will return the value for a new errorcode in the same deterministic way on all processes. ( End of advice to implementors.)

exception UnicodeTranslateError¶ Raised when a Unicode-related error occurs during translating.

If, for example, execution synchronously passes through a C++ addon function called cheetahify, which itself calls a JavaScript function, the frame representing the cheetahify call will not be present in the Such exceptions will always cause the Node.js process to crash. Live curious. All Exception Classes Inherit Either Directly Or Indirectly From For example, file errors would normally be sent to the file error handler. ( End of advice to users.)
