Triggered by recent code size discussions in the jQuery community, I’ve thought a little bit more about the “all dancing all singing 20KB jQuery core limit” which is often stated. You have not heard about this until now? Well, for acceptable reasons jQuery core is meant to be not larger than 20KB and to still reach this goal people optimize the jQuery core code by single characters — even if it IMHO sometimes obscures the code to some extend.
First, the “packer” compressed jQuery SVN as of today is 20961 bytes which actually is 20.46KB. Well, I’m personally fine with this. But I’m personally also fine with a jQuery of 30KB or even 40KB in size — as long as great functionality and stability is provided. And I can image that most people also care more about other factors than about a few KB more or less.
