Consider the following example:

function myFunction() {

var mytext = "Mytext";

function showtext() {

console.log(mytext);

}

showtext();

}

Function myFunction declares a local variable mytext and a function showtext - the inner function defined inside myFunction() that is available only in the body of myFunction. here, showtext has no local variables, but it has access to those of its outer functions, in this case myFunction. Within the myFunction body, we call the showtext function in order to displayed the text contained in variable mytext.
