I have this HTML document:
<!DOCTYPE html>
<html>
<body>
<script type="text/javascript" src="/first.js"></script>
<script type="text/javascript" src="/second.js"></script>
</body>
</html>
first.js:
(function(){
var p = 9;
...
})();
How to have access and edit the p variable from second.js without modifying first.js? Is there a way?
