JS API 3.4 how to use dojo?

[UldisGitendorfs]

I do not understand how and when to use

require([
        "dojo/_base/connect",
        etc.],
        function(connect) {
          });
and when
dojo.require();

I have tried to use require([]) ... but nothing works.
Do I have to use this before any function???

Are there any extended examples on the net?

Don't use dojo.require().  That is the old way to do things. You should use the AMD method for new development.

Here is a sample on JSFiddle. Here's the same sample on Plunker.

Thanks for posting a sample Jeff. His sample is adapted from this tutorial:

This link goes over the new AMD style using require:
