In computer programming, a nested function (or nested procedure/subroutine) is a function which is lexically (textually) encapsulated within another function. It can only be called by the enclosing function or by functions directly or indirectly nested within the same enclosing function. In other words, the scope of the nested function is limited by the enclosing function. The nesting is theoretically possible to any level of depth, although only a few levels are normally used in practice.

Famous quotes containing the words nested and/or function:
“I was asking for something specific and perfect for my city,
Whereupon lo! upsprang the aboriginal name.
Now I see what there is in a name, a word, liquid, sane, unruly,
musical, self-sufficient,
I see that the word of my city is that word from of old,
Because I see that word nested in nests of water-bays, superb,
Rich, hemm’d thick all around with sailships and steamships, an
island sixteen miles long, solid-founded,”
—Walt Whitman (1819–1892)
“It is the function of vice to keep virtue within reasonable bounds.”
—Samuel Butler (1835–1902)
