Editing Nested function (section)

== Value ==

The nested function technology allows a [[programmer]] to write [[source code]] that includes beneficial attributes such as [[information hiding]], [[encapsulation (computer programming)|encapsulation]] and [[Decomposition (computer science)|decomposition]]. The programmer can divide a task into subtasks which are only meaningful within the context of the task such that the subtask functions are hidden from callers that are not designed to use them.

Block scoping allows functions to share the state of enclosing blocks (including enclosing functions) without passing [[Parameter (computer programming)|parameters]] or using [[global variable]]s.{{sfn|Bright|2004}}
