How to Encode JavaScript files?

Question

How can I encode my JavaScript file like DLL files?

I mean nobody can understand the code like Dll created from CS file in C#. I need this because I want to give my functions to some company, but I do not want they to understand inside my functions....just can call the functions.

I see the jQuery files are encode to variables (a,b,c,d,....). for example encode this simple code:

function CookiesEnabled() {
var result = false;
createCookie("testing", "Hello", 1);
if (readCookie("testing") != null) {
    result = true;
    eraseCookie("testing");
} return result;
};

There really isn't any way to encrypt/encode code like that in JS (at least I do not know of any way), but the standard way is to use good minifiers i.e. programs that collapse your code, remove comments rename local variables from good long names to stuff like width and height to stuff like a and b. And even re-structure your code so its as compact as possible. They usually end up non-human readable.

Minifing is usually even called JS compiling, but its not really. As with is a good one, well not going to go there, there are so many, but for my purposes I've been using the Microsoft official bundler:
