Can you help me understand the benefit of require.js?

I'm having trouble understanding the benefit of require.js. Can you help me out? I imagine other developers have a similar interest.

From Require.js - Why AMD:

The AMD format comes from wanting a module format that was better than today's "write a bunch of script tags with implicit dependencies that you have to manually order"

I don't quite understand why this methodology is so bad. The difficult part is that you have to manually order dependencies. But the benefit is that you don't have an additional layer of abstraction.

NodeJS (or CommonJS?) code to recursively traverse directories triggering the provided callback each time a regex matches a file name.
var fs = require("fs");
/**
* Call fileHandler with the file name and file Stat for each file found inside

* Call the optionally provided completeHandler with an array of files (mingled

first whack at pagination with backbone.js
// includes bindings for fetching/fetched
PaginatedCollection = Backbone.Collection.extend({
initialize: function() {
_.bindAll(this, 'parse', 'url', 'pageInfo', 'nextPage', 'previousPage');
this.page = 1;
},
fetch: function(options) {
options || (options = {});
this.trigger("fetching");
// 1: how could you rewrite the following to make it shorter?
if (foo) {
bar.doSomething(el);
} else {
bar.doSomethingElse(el);
}
