In this tutorial we're going to build a set of parser combinators.

What is a parser combinator?

We'll answer the above question in 2 steps.

So first question: What is parser?

Convert a flat representation of a hierarchical data into a nested tree structure.

The dataset is already sorted
The dataset should be in the form of an RDBMS resultset, however that is represented in your target language
Multiple "top-level" nodes may exist, defined as having an empty parentId

#Roost Chicago 2014 Q&A

Is there any reason you're using the require() inside a define() rather than simply declaring the dependencies in the define(), such as define('backbone', function(backbone) { ... });

the problem with using requires inline rather than declaring dependencies that a race condition for loading may happen. define() and require() are slightly different

in app code, it's really a matter of style. listing deps in an array is the AMD format, using require is the CommonJS style. A script loader has to parse the CommonJS format to build up the AMD-style array before it runs, but otherwise they behave the same
Can someone please remind me what $el refers to in `this.$el.empty()'?
