Using nested functions in JavaScript In JavaScript, a function can be defined inside another function. Such functions are called nested functions or inner functions. Nested functions have access to the variables and parameters of the outer function, as well as to the global variables and functions....
In this article we learned that when a function is not specified as a method of an object, the JavaScript “this” keyword refers to the window object. This is true even in the case of nested functions. In fact, no matter how many levels deep we nest functions, the JavaScript “this”...

Here’s an example of what nested functions in Javascript would look like: function circumference (radius) { // nested function: function diameter() { //note the use of "radius" - a parameter of outer function return 2*radius; } // call the nested function return Math.PI * diameter(rad...
Nevertheless, the programming idioms in untyped, or dynamic, languages make heavy use of features--run-time type tests, mutable objects indexed by dynamically computed keys, prototype inheritance, and higher-order functions--that are beyond the reach of prior type systems. Because of the rising ...
A nested function is defined as a function which is defined inside the definition of another function. Programming languages like c, java, etc do not support nested functions but Scala does.In Scala, nesting of functions is possible and there can be multiple function definitions to be called ...
