Quite often when building web pages we tend to rely on certain techniques trying to make the users “play by the rules” and utilize the web pages in a predictable way. In fact, we rely on them so much that sometimes we forget that their power can be turned against our purpose.
Indeed, JavaScript, “the great and the mighty” can become a dangerous weapon in skillful hands and used not to our advantage.

Once you realize how easy it is for a “total stranger” to “beat up” your web page you may decide to review your good techniques and utilize other tools to strengthen the “line of defense”.
