Pointless article, JS is not competing with ActionScript in the way that the author compares it.

Most of the time your app will probably be slow because of the DOM interactions, not because of your JavaScript, most time is usually spent in the rendering and fetching stuff from the network.

To give a better viewpoint: You won't write a database engine in Ruby or PHP, you will write it in C, C++, Java, but you will use PHP/Ruby to interact with it.

We have low level programming and high level programming for these distinct purposes. I am sure that if you won't write something in JavaScript you will probably not write it in ActionScript either.
