It's not really AJAX, it's just loading in the js files by injecting
<script> tags into the DOM.
require() in it's synchronous form makes sense in the context of node, it
does not in the context of the browser.
Say you have moduleA, moduleB and moduleC and they all require moduleZ.
Using browserify, you have to inject moduleZ into moduleA, moduleB and
moduleC. If moduleZ is 30kb of javascript, this is a huge issue.
This is just one of the reasons why taking the async approach works better,
it does what node does synchronously, a synchronously. require() accepts a
string, tries to map that path to a file, includes that file, etc. in the
process of doing this, it caches that js file. Thus, calling require("foo")
100 times, does not have the overhead of require("foo") x 100.
You can not get require("foo") working in the browser the same way that
node implements it. You can however, get an async approach to this problem
implemented in node. You need some way for the browser to resolve "foo" to
an actual file, load that file, and upon loading that file, invoke a
callback function.
This is a problem that RequireJS, MinionJS and dojo all handle and this is
the right approach the problem.
Browserify is a cool project, but it's usefulness ends as soon as you step
into real world applications.
