I have to write every function i need for CouchDB?

In MongoDB you have a lot of helper methods 开发者_StackOverflow中文版that do all the basic operations for you:

• count
• sort
• update
• replace
• etc...

In CouchDB you ahve to write map-reduce for everything by hand for basic operations?

There are some built-in functions for CouchDB and there's a CommonJS implementation for CouchDB.

It's all Map / Reduce functions.
