Client side Ajax development is more suitable for web applications that have complex user interaction since its doesn’t consume server resouces to update the UI.
But off course, your app logic still remains on server side.

I use Microsoft Ajax Library to simplify client side development. This Ajax Library is a rich framework and used extensively at client script.
