Build a Family Tree 👨‍👩‍👧‍👦

Family Tree

---

Trees are such an important structure in computer science. But what more important tree, than our family tree? ❤️ 👨‍👩‍👧‍👦 ❤️

For this weekend assignment, you will have to build a tree that has multiple children. It will have a few methods:

familySize: Returns this size of this parent and their children.

findMember: Given a name, it will return the node where that member exists. Otherwise, returns undefined.

log: Logs out a specific structure (exampled below) of the family from this point down.

insert: Inserts a child at this node.

---

I've been kind enough to have written a suite of tests to help you get there. But I am ok with you doing this outside of this repo, on your own, as long as the work you turn in on Monday can operate like the example below.

const szwajkowskis = new FamilyTree('Pops');

szwajkowskis.insert('Mike');
szwajkowskis.insert('Amy');
szwajkowskis.insert('Todd');

const mikesFamily = szwajkowskis.findMember('Mike');

mikesFamily.insert('Eliot');
mikesFamily.insert('Elise');
mikesFamily.insert('Cas');
mikesFamily.insert('George');
mikesFamily.insert('Lear');

const amysFamily = szwajkowskis.findMember('Amy');

amysFamily.insert('Henry');
amysFamily.insert('Vivian');

const log = szwajkowskis.log();
console.log(log);

// Logs:
/*
-- Pops
---- Mike
------ Eliot
------ Elise
------ Cas
------ George
------ Lear
---- Amy
------ Henry
------ Vivian
---- Todd
*/

Using This Repo

To use this repo, the following instructions should be followed.

1. Pull down this repo from github.
2. At the root level of this repo, run npm i to install all dependencies.
3. Write code in the adjacent file family-tree.js.
4. While writing that code, you can at any time run npm run test to see results of how you are doing against the tests in the terminal. If you want to see live results of how your code is doing, you can run npm run test:watch
5. When passing all tests push up to your own personal fork!

Extra

If you're unimpressed by the difficulty of this assignment, I would ask that you make the family tree that you've designed in JS look like a family tree in HTML! Build a HTML file that renders the tree and allows you to add additional family members. You can watch the GIF below to see what I am talking about (ignore the setup I use in the GIF, just the webpage matters).
