The code which forbids to look at the code of an element on a web page?

Question

JavaScript

Code that prohibits viewing the code of an element on a web page

Answer 1

You can only disable the right mouse button, but you can still download the entire page.
Forget it. The page code is not protected.

Answer 2

Code that prohibits viewing the code of an element on a web page

Where?

Well, maybe I said it incorrectly, but I need a code that, when the right mouse button is pressed, a message pops up
something like that

document.oncontextmenu = function(e){ 
  e.preventDefault();
  alert("А нельзя"); 
}

Answer 3

You are trying to "protect" HTML "code". It's impossible.
