Avoid jQuery When Possible

jQuery does good jobs when you're dealing with browser compatibility. But we're living in an age that fewer and fewer people use old-school browsers such as IE <= 7. With the growing of DOM APIs in modern browsers (including IE 8), most functions that jQuery provides are built-in natively.

When targeting only modern browsers, it is better to avoid using jQuery's backward-compatible features. Instead, use the native DOM API, which will make your web page run much faster than you might think (native C / C++ implementaion v.s. JavaScript).

If you're making a web page for iOS (e.g. UIWebView), you should use native DOM APIs because mobile Safari is not that old-school web browser; it supports lots of native DOM APIs.

If you're making a Chrome Extension, you should always use native APIs, not only because Chrome has almost the latest DOM APIs available, but this can also avoid performance issue and unnecessary memory occupation (each jQuery-driven extension needs a separate

Most examples I found tell you to run rvmsudo or passenger-install-nginx-module. I ran into problems with these because:

rvmsudo leaves root owned directories and files under rvm passenger gem directory. This will give you seemingly odd errors later when you try to remove/upgrade passenger gem, or try to use homebrew to install passenger.
There's no good place to put nginx using passenger-install-nginx-module. Putting it under /usr/local means you have to remember it's there amongst homebrew files. Anywhere else, you still have to remember you put it there. We'd rather manage nginx install via homebrew.

So to install everything with homebrew, this is what it took:

gem install passenger
