So, you are using a bunch of javascript libraries in a website. Your javascript code calls the several APIs, but every once in a while after an upgrade, one of the API changes, and your code breaks, without you knowing it.

How do you prevent this from happening?

I'm mostly interested in javascript, but any answer regarding dynamically typed languages would be valuable.

Someone on the Herding Code podcast No. 68, http://herdingcode.com/?p=231, stated that IOC containers had no place with Python or Javascript, or words to that effect. I'm assuming this is conventional wisdom and that it applies to all dynamic languages. Why? What is it about dynamic languages that… >>> More
Which conveniences does CEDET bring to dynamic languages ?

I've been looking into CEDET, but it seems that most of its features would appeal more to developpers working in statically typed languages, and I'm kind of getting cold feet from the amount of tinkering it seems to require.
