The creation of a nested function is fairly simple: just declare the function as it is normally done, only within the scope of another function. Nested functions have access to the variables declared in the outer function, just like functions have access to the variables declared outside of the functions.

This can be useful when creating nested functions, as much of the code can be put into a nested function without needing to declare a parameter for every single variable in the function. If you want to use a value that is in the outer function in the nested function without modifying it by accident, you can always pass the value as a parameter. Note that the examples on this page are purely for the ease of learning nested functions; replacing each line in a function with another function is unlikely to be a good idea.

Typically, these should be used to separate different logical chunks of code, to help clarify the code. The benefit of nested functions is more apparent when the functions are significantly larger; often dozens of lines long, or more. This is a guide to Javascript Nested Functions.
