hope to see more closer reviews and examples :)

Of course, most of the components are available separately for each framework, but because these are “built-in”, it’s a guarantee that all of them are easily extendable, are coded in the same manner, etc.

I guess using it in production depends on the project, being so verbose means there is more code to write, maintain, and so on.

For small projects, no discussion, any framework will get you the same results faster. For larger projects with a bigger codebase, the scalable nature of Closure could make it easier in the long run.

Also, the Closure Compiler keeps file size small, and the tests i’ve run indicate that the bigger the initial file, the greater the percentage it’s size it’s reduced by.

Would you use it in production instead of Prototype+Scripta?

Myself, I’m in love with jQuery… :)
