#### Editor’s note
 
I’m here for static pages revival. No problems loading text, no delayed or failing script execution issues, much better resilience on slower connections are just a few potential benefits. Is it possible to make a static page slow? Sure, if we tried hard, but most severe performance issues are attributable to scripts.
 
While it might not be possible to build rich applications without JavaScript, it’s possible to add script responsibly. Static sites went from default to obscure, why don’t we reverse the trend?
