> "JS MVC frameworks: MVC in JS is almost always overkill." This depends entirely on what you're making. JS frameworks like AngularJS really ease the pain of building rich, interactive web apps. > "HTML5: Most of the web doesn't have support for it yet." HTML5 is a moving target, modules are now versioned separately so there is no true/false for support. The fact is you can use a lot of the really useful changes so far in the most used modern browsers and there's polyfills/shivs to help IE9 and below. Now that we're all moving to auto-updating browsers we should see a much faster rollout of new features than we have in the past. > "Optimization: go looking for the tools once your app tells you it's slow" If you can solve a problem before it happens then you should do it, it should be part of your deployment process. If you're just making simple sites then apps like CodeKit can take care of everything for you. > "damn it's a pain to debug your live site." So don't try to debug a live site, that's silly!
