Question

I am having a hard time understanding Static scope in Javascript. Can anyone please explain the difference between the below two functions

It works fine if I do

function sayHi(){
        alert("Hi");
    }
    sayHi.alternate=function(){
        alert("Hola");
    }
    sayHi();
    sayHi.alternate();

But doenst work if I do

function sayHi(){
        alert("Hi");
    }
    function sayHi.alternate(){
        alert("Hola");
    }
    sayHi();
    sayHi.alternate();

As usual Thanks

This isn’t valid javascript:

function sayHi.alternate(){

You can’t assign a property when declaring a function this way. You can only define a name to be used for the function. That’s why the other form is used when you’re assigning it to an object property or assigning to a variable.
