[Attendance Tracker]

Pitch

Logging the attendance of each student via the main router of an establishment that checks mac addresses.

Problem

Logging attendance manually can be tedious as well as error prone. It wastes precious time.

Array Prototype Methods

I understand that functions in JavaScript can take any number of arguments. 3

I can describe the similarity between blocks in Ruby and anonymous functions in JavaScript. 3

Where are the methods available to all arrays (e.g. forEach, map, etc.) defined? 2

I can explain the difference between using a for loop and the forEach method. 3

I can explain the difference between function declarations and function expressions. 3

I can explain what the value of this is in a normal function. 2

I can explain what the value of this is when called from the context of an object. 2

I can explain how to explicitly set the value of this in a function. 3

I can explain the difference between call and apply. 3

Step One: Watch Sorting Algorithms in JavaScript

Step Two: Fork this gist.

Step Three: Respond to this question in your fork: "What are some of the balances and trade offs between different sorting algoritms?"

• Bubble sort is just the slowest one ever. It checks every single element all the time. No bueno
• Merge sort is the best. Requires more memory for storing sorted left and right arrays, but the speed is much faster
• Insertion sort is good for arrays that are not too unsorted and remains fast until the order/size is to unordered/big

Step One: Watch Writing Testable JavaScript - Rebecca Murphey from Full Frontal 2012 (award for worst conference name ever?)

Step Two: Fork this gist.

Step Three: Respond to this question in your fork: Consider the four responsibilities that Rebecca lists for client side code (hint: they're color coded). Respond below with your thoughts. Did any of the responsibilities that she lists surprise you? Do you feel like you mentally split your client side code in IdeaBox and other past projects into these responsibilities?

Step Four: Totally Optional: take a look at some of the other forks and comment if the spirit moves you.

Step One: Watch Mary Rose Cook Live Codes Space Invaders from Front-Trends. (The second worst conference name ever?)

Step Two: Fork this gist.

Step Three: Respond to this question in your fork: What is one approach you can take from this Mary's code and implement in your project?

I can mitigate which classes are responsible for what actions. I like how she was using emacs :)

In tron I find it difficult to load two bikes in the game object. This code seems to be nice and broken into manageable pieces!

const _ = require('lodash')

class TronBike {
  constructor(grid, x, y, width = 20, height = 20, color) {
    this.grid = grid
    this.x = x
    this.y = y
    this.width = width
    this.height = height
    this.position = 1
