Hello - welcome to the ./slides and ./exericse for my quadtrees talk!

I've made some notes in NOTES.md about things I found interesting as I coded up my implementation. Maybe you'll spot some interesting things about the algorithm too!

If you do run into issues today, first off: sorry! Secondly please file an issue.


Pre-requisites:

• Node >= 6.0.0 (you can use nvm if you have another version)
• Chrome

npm install

npm start

## Exercise

There are two parts - first the unit-tests, which you can complete in TDD style. Secondly the example where you can see your image displayed!

cd exericses
npm run tddd

This will kick off mocha, and re-run the tests each time you make a change. Avoid using DOM APIs in your index.js as the tests run in Node. All browser-related stuff lives in demo.js and is taken care for you!

cd exercises
npm start

This will open a browser window with your code running! It will live-reload as you make a change.

There is a working example in example.js. Try not to use it! :) If you're stuck and it feels like the system is at fault, not you, set the VS_EXAMPLE env variable to anything. The tests and demo will then work vs the example, e.g:

VS_EXAMPLE=1 npm start

# or
VS_EXAMPLE=1 npm test
