Visibility of Nested Functions
Every function has a certain scope, that is, a set of other functions to which it is visible. A
nested function is available:
- From the level immediately above it. (In the following code, function A can call B or D,
but not C or E.) - From a function nested at the same level within the same parent function. (Function B
can call D, and D can call B.) - From a function at any lower level. (Function C can call B or D, but not E.)
