Warmup

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

The comments data is imported as data.comments.

How many people have submitted comments?

// TODO: write code to answer this question
return _.size(data.comments)

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)
console.log(text.split('\n'))

// TODO: add code to process text to get the person's favorite food

return _.last(text.split("Favorite Food:"))

So, willzfarmer's favorite food is Sushi.
