Utility Functions

You should employ full TDD as you build these functions.

If you need extra guidance refer back to your schema in the migrations files and look at how the data provided differs from the structure set out in the schema.

---

formatDate

This utility function should be able to take an array (list) of objects and return a new array. Each item in the new array must have its timestamp converted into a Javascript date object. Everything else in each item must be maintained.

hint: Think carefully about how you can test that this has worked - it's not by copying and pasting a sql timestamp from the terminal into your test

---

makeRefObj

This utility function should be able to take an array (list) of objects and return a reference object. The reference object must be keyed by each item's title, with the values being each item's corresponding id. e.g.

[{ article_id: 1, title: 'A' }]

will become

{ A: 1 }

---

formatComments

This utility function should be able to take an array of comment objects (comments) and a reference object, and return a new array of formatted comments.

Each formatted comment must have:

• Its created_by property renamed to an author key
• Its belongs_to property renamed to an article_id key
• The value of the new article_id key must be the id corresponding to the original title value provided
• Its created_at value converted into a javascript date object
• The rest of the comment's properties must be maintained
