Undefined value: Art, Handling & Overview

In computing (particularly, in programming), undefined value is a condition where an expression in a programming language does not have a semantically correct value in the language, even though it is syntactically correct. An undefined value must not be confused with empty string, Boolean "false" or other "empty" (but defined) values. Depending on…
