Is there an API available for SharePoint 2010's JavaScript based Client Object Model?

Question

I've searched the farthest reaches of the internet, but I cannot find an online API for SharePoint 2010's JavaScript based Client Object Model.

Answer 1

Assuming with online API you mean the MSDN documentation you can find it in this MSDN article: ECMAScript Class Library.

You should search Google for "Sharepoint 2010 ECMAscript" and you will find many useful articles explaining its use.
