There is no “javascript” [1] and YSCIB.

Please take more when writing your Usenet articles.

Learn pretty printing to make source code easily readable

  function myFunction (a, b)
  {
    return a * b;
  }

Syntax error.  “int” is a *future* reserved word; these languages are 
*dynamically* typed.  Perhaps you were looking for

  for (var i = 0; i < 10; ++i)
  {
    document.getElementById("demo").innerHTML = myFunction(4, 3);
  }

Which begs the question: Why do you want to execute this 10 times?
Why do you expect the result of the first iteration to be different
from that of the fifth or the tenth?

Accessing an element before the document has been loaded, like this,
also is not reliably.  Move your code to a function that you call from

  <body … onload="…">
    …
  </body>
