I can't believe that single page webapp are easier to write than true old website. Maybe you can gain some performance improvement but if you use a framework you will loose this very little gain. Those who claims that developpement is easier with framework on a single page have too learn programming, because for most case, the "old" way works very well and is incredibly faster than a bloated javascript page.

I really, really dislike this approache of doing website, it make the code and the design hard to understand and cost a lot of problem when comes the time to debug or made major changes.

There are no magic when using javascript, it will slow down the client, and manipulating DOM is very slow. Doing things server side cost nothing compared to javascript. Remember that loading a webpage is very fast when you have only a CSS and html code, because it very easy to put it in cache and doing some pretty nice optimizations on it.

With frameworks, making "webapp" become a huge nigthmare, things becomes overly complex and bloated, the request as to pass trough a lot of layers before end up somewhere, and the developpement is not faster than have a custom code. Good framework don't make good programmer.

When the article say "put the CSS inside a <style> tag on the page - and the JS inside a <script> tag", it's just horrible, fuck it.
