The Story of Google's Closure: Advanced JavaScript Tools

What he doesn't tell you is how much the Reader code would be if it was just gzipped. That's the real comparison to make.<p>If gzipping alone would get the code down to 800kb or something, then the improvement made by closure doesn't seem so awesome.<p>Nonetheless, it's obviously good to get the file size down to the absolute minimum when you are going to serve millions or billions of copies.

I find this whole Closure story amusing, because what it amounts to is applying static typing techniques to a dynamic language - and guess what, static typing makes "it easier to catch errors much earlier". Where are the dynamic typing extremists when you need them?

<i>Mihai estimates that without Closure, Reader's JavaScript code would be a massive 2 megabytes</i><p>Wow. That just seems wrong to me.

I'd be interested to know how it compares to the current version of Dojo.
