Test if JavaScript has been modified
<p>I have coded a basic game in JavaScript and am working on a high score system for it, however as it is coded in JavaScript we all know it is incredibly easy to open Firebug or Chrome's Dev tools and edit the code. For example adding a multiplier to the score.</p>

<p>Does anyone know either
A) a way to check the JavaScript hasn't been modified and/or 
B) a secure way to post the scores</p>
