Warmup

As warmup, let's being with some simple questions.

The comments data is imported as data.comments.

How many people have submitted comments?

return data.comments.length

There are 26 submissions.

Who is the first person submitting a comment?

We can get the data of the first comment by

// TODO: use lodash's method instead of direct array access via [0]
return _.first(data.comments)

The result is

{
 "url": "https://api.github.com/repos/bigdatahci2015/forum/issues/comments/133203904",

}

The person's name is willzfarmer.

What is willzfarmer's favorite food?

We will need to parse the comment to retrieve this data.

The comment text is

"Name: William Farmer\r\nMajor: Applied Math w/ Minor in Computer Science\r\nFavorite Programming Language: Python\r\nFavorite Food: Sushi"

The code to retrieve the data about the favorite food is (hint: use split()).

var text = _.first(data.comments).body
console.log(text)
var text1 = text.split('\nFavorite Food:')
var favoritefood = _.last(text1)

return favoritefood

So, willzfarmer's favorite food is Sushi.
