Given an anonymous function, this can be done either by binding a name to the function, as in named function expressions in javascript, or by assigning the function to a variable and then calling the variable, as in function statements in javascript Since languages that allow anonymous functions generally allow assigning. An immediately invoked function expression (or iife, pronounced iffy, ipa /ˈɪf.i/) is a programming language idiom which produces a lexical scope using function scoping It was popular in javascript [1] as a method of supporting modular programming before the introduction of more standardized solutions such as commonjs and es modules [2] immediately invoked function expressions can be. Function reference passed to and called by another functiona callback is often back on the level of the original caller
In computer programming, a callback is programming pattern in which a function reference is passed from one context (consumer) to another (provider) such that the provider can call the function If the function accesses state or functionality of the consumer, then the call. In some programming languages, function overloading or method overloading is the ability to create multiple functions of the same name with different implementations Calls to an overloaded function will run a specific implementation of that function appropriate to the context of the call, allowing one function call to perform different tasks depending on context. Call graphs can be dynamic or static [4] a dynamic call graph is a record of an execution of the program, for example as output by a profiler
A static call graph is a call graph intended to represent every possible run of the program The exact static call graph is an undecidable problem, so static call graph. [5] the same technique is used in the avisynth.
