Symbols are a one off version of a string and are more memory efficient.



Hashes are a collection or set of key value pairs.

who_am_i = {
  :first_name => "Benjamin",
  :last_name => "Spak"

=> "Benjamin"

Method is a block of reusable code.

def good_morning
puts "Good Morning"

Unless is the opposite if an if statement. It only runs if false.

age = 22
unless age > 65
puts "You're a yougin"

.each method. A method can accept one or more parms within pipe | chartacters.

list = [1, 2, 3, 4, 5]
list.each do |number|
puts number * 8

Still mostly touching code at work.

Day 15 - 17

Worked on & learning the ropes at my new contract with Wells Fargo.

Day 14 | Part 1 | 9.14.2018

Woo! Learning CS is fun again! Very excite! For more Data Structures and Algorithms in JavaScript - Full Course for Beginners

Cheers to Scott Diemer for mentioning on Twitter that I can just use an -a flag in place of git add . when stringing Git CLI commands.Re: Day 13s Tweet.

Want to expand my programming awareness a little bit today. Watching Robert C Martin - Functional Programming; What? Why? When?

Side Note: CS50 wasn’t a total waste of time – still won’t continue it – but, now I’m familiar with C syntax – which Uncle Bob likes writing his examples in.


1; // a value
in x=1 // x is an id that has a value.
x=x+1; // now x has changed state.

The final above line is stateful – ideally, to build more fault tolerant code we want stateless code – no variable is altered.

Thought: Ah! So this is why I’m seeing const for variable assignment more often in JS than let or var. I thought I knew, but this adds an extra level of WHY it is done; huzzah!

Stateful code is liable to cause memory leaks – garbage collection is a merly a hack to deal with the side effects of stateful code.

Why Functional Programming?

👀 “scala vs haskell” 👀 “scala vs go” 👀 Making The Move From Scala To Go, And Why We’re Not Going Back

Ah!!! Recalled from D 12 “All React components must act like pure functions with respect to their props.”

Now we’re cooking with gas! Love it when to seemingly unrelated topics – Reace Function Porgraming matach up and reenforce learning to two areas!

Okay – now - back to CS.

Queue - Data Structure

Main methods of a queue in JS:

Tree – Data Scructure

From personaly experience – working with the DOM – I’m familiar with grand parent & grand children nodes being used to label things as well.

Biary Search Tree – Data Scructure

On average - operations are able to skip about half of the tree.

Common Datatypes CS50 - Week 7 – part 2


Linked List

… Okay, I’m looking for another CS recourse; CS50 is horrible at providing concise lessons …

Data Structures and Algorithms in JavaScript - Full Course for Beginners

Stack - Data Structure

JavaScript already has all of the array functions necessary to use it as a stack.

Sets - Data Structure

Day 12 | Part 1 | 9.12.2018

CS50 Week 5 - part 1

Finally decided to complete CS50 so I have a basic grasp of how low level languages work. Only 7 more weeks worth of videos. At my current pace I’ll be done in 1 - 2 weeks.

CS50 Week 5 - part 2

Lecture 63 + Jr -> Sr. Dev Course

Day 12 | Part 2 | 9.12.2018

Going through the React tutorial; show provide better solid rules, methodologies & principles to follow for React.

const title = response.potentiallyMaliciousInput;
// This is safe:
const element = <h1>{title}</h1>;

JSX Represents Objects
Babel compiles JSX down to React.createElement() calls.
These two examples are identical:

const element = (
  <h1 className="greeting">
    Hello, world!
const element = React.createElement(
  {className: 'greeting'},
  'Hello, world!'

Note: Always start component names with a capital letter.

All React components must act like pure functions with respect to their props. Community Development

CS50 Week 7 – part 2

Day 11 | Part 1 | 9.11.2018

CS50 Week 4 – Part 2

More C syntax and swapping numbers in an array. 💤

Day 11 | Part 2 | 9.11.2018

Jr to Sr Dev Course – Lecture 60 - 63

import React from 'react';

const Card = (props) => {
  const { name, email, id } = props;
  return (
    <div className='tc bg-light-green dib br3 pa3 ma2 grow bw2 shadow-5'>
      <img src={`${id}?200x200`} alt='robots' />


export default Card;

Re-watch lecture 63 before work tomorrow

Day 10 | 9.10.2018

CS50 Week 4 – Part 1

Merge Sort Algo

On input of n elements:
  If n < 2
    Sort left half of elements.
    Sort right half of elements.
    Merge sorted halves.
Cut the arrary in half
  Sort the left 1/2 of the original array
    Sort the left 1/2 of the left 1/4 of the split array
    Sort the right 1/2 of the left 1/4 of the split array
  Merge / group - the split 1/4 arrays into ordered 1/2 arrays
  Merge / group - the split 1/2 arrays into a reordered whole array

Efficacy T(n) = 0, if n <2

T(n) = T(n/2) + T(n/2) + n, if n > 1
T(16) = 2xT(8) + 16
T(8) = 2xT(4) + 8
T(4) = 2xT(4) + 4
T(2) = 2xT(1) + 2
T(1) = 0 <-- Base Case

Cool! Plateaued on Big O notation. Will need to stop and review tomorrow.

Jr to Sr Dev Course – Part 4 – React, Redux + Bundling

Haven’t been sleeping well, crashed out for a couple of hours after my first day with Well Fargo. So far so good, chill company & team.
Starting with React in the course. Should be an informative refresher.

Day 9 | 9.9.2018

Starting The Complete Junior to Senior Web Developer Roadmap (2018) – On Udemy

Now using ^^ to denote something to look up tomorrow.
Now using ==> to denote a topic / task has been pushed from the previous day.

Made it though the SSH section of the course. It’s 2am. Going to try to sleep again.

Pick up here

Day 9 | Part 2 | 9.9.2018

Now including search queries. Denoting with eyes emoji 👀.
Using ... alternatively for searching or to denote time has passed.

CS50 Week 2 – Part 1

The Complete Junior to Senior Web Developer Roadmap – Section 3 - Performance

Why we need performant websites

Network Optimizations

  1. Minimize / uglifiy text files – HTML, CSS, JS.
  2. Minimize images.
    • SVG, JPG, PNG, GIF, WebP
    • File format use cases
    • Always lower JPG image quality to 30% - 60%
    • Resize image based on size it will be displayed.
    • Use media queries to display different size images based on browser window size / client.
    • Use CDNs like imigx to serve images.
    • Use a tool such as verexif to remove image meta data.
  3. Use light wight frameworks that contain smaller, less files.

Critical Render Path

DOM --> CSSOM --> Render Tree --> Layout --> Paint |




Prefetching, preloading, prebrowsing

After going though a solid portion of this content I realized I researched many of these concepts while working @EBG in order to get Adobe Target experiences to be more performant – also had to use setTimeout() often haha.

However, I never wrote them down. It’ll be nice to now have written cheat sheet / check list to come back to.

“Premature Optimization is the root of all evil” 🔥🔥

CS50 Week 2 – Part 2

The first part of this video is just C syntax and C caveats … 💤
Stanford algos may be up next 🤔
Skipped ahead about 20 min. Just talking about square bracket selection of indices & arrays.
hmm 🤔 they are talking about crypto in week 3. Okay, I’ll check it out.

CS50 Week 3 – Part 1 & 2 Thank god to 2x speed – 2x video speed is BAE ❤️ j/k Youtube Playback Speed Control and 3X is BAE ❤️️ It really is the simple things in life … 🔥🔥
hahah man, if I were paying for this course from Harvard I would be pissed; it’s super redundant – they are calling back to the algo in week 0.

Woo! Okay, sorting algo @ 16 min in. Time to slow it down :)

Bubble Sort Algo

Check number to right of current number
if number to right is smaller
  move that number to the left
if no sorting took place
  sorting is complete  

Efficacy == n squared -- in theory

Selection Sort Algo

search and store smallest number
then check the rest of the data for a smaller number
if a smaller number is found, store that number and let go of the previously stored number
then after checking the entire set of numbers, move the ultimate smallest number to the start of the set.
as an optimization, ignore the known smallest number
if a larger number is in the the index of the next smallest number you would like to store, swap the place of the larger and smaller number to place the smaller number in the correct location
  repeat the above pattern for the next smallest number until the sequence is complete

Efficacy == n squared -- in theory

Insertion Sort Algo

take the first index and mark it as sorted
check the next unsorted index and compair it to the previous sorted index.
move the smaller of the indices to the left; within the sorted indices.
then sort the stored set similarly to the selection sort algo ...

Efficacy == n squared -- in theory

Day 8 | 9.8.2018

Continuing CS50 – Week 1

Week 1 – Part 1 – Notes Now using | to denote simple Googleable/familiar concepts for brevity.

Week 1 – Part 2 – Notes

Downing energy drinks because I wanted to be productive. On to the second video …

New concepts:

hmm … may dip in and out of a few videos so I can skip to things I may be unfamiliar with. Or, I think stanford has quality algorithm videos online; may switch to those. TBD.

Day 7 | 9.7.2018

Watching the first video of Harvard CS50. Had gone through the course before, but I wasn’t experienced enough to grasp most of the applicability. Now, I’m excited to marry CS theory with my coding experience!




What’s an algorithm?

Ted Ed Explainer Video

What is Pseudocode?


let N = 0
for each person in room
  set N = N +1

In other words:
For each person in the room we will increase our count N by 1.

Optimization of the above algorithm

let N = 0
for each pair (2) of people in the room
  set N = N + 1
let N = 0
for each pair of people in room
  set N = N + 2
if 1 person remains then
  set N = N + 1

Day 6 | 9.6.2018



Day 4 & 5 | 9.4.2018 - 9.5.2018

Haven’t been tinkering with code as much as I’d like to the past couple of days. However! I put to two websites from Wordpress templates to help our community.

Day 4 | 9-3-2018

Was working on the startup, building out the squad, hosting a few meetings & figuring out new social media marketing strategies for the podcast, twitter, Instagram & YouTube. Finally back to Node :)



(req, res, next)
exports.myMiddleware = (req, res, next) => { = 'Wes';
router.get('/', storeController.myMiddleware, storeController.homePage);


Example schema:

const storeSchema = new mongoose.Schema({
  name: {
    type: String,
    trim: true,
    required: 'Please enter a store name!'
  slug: String,
  description: {
    type: String,
    trim: true
  tags: [String]

If you want to use these this keyword you need to use the function keyword instead of ES6 arrow frunctions.

storeSchema.pre('save', function(next) {
  if (!this.isModified('name')) {
    next(); // Skip it
    return; // stop this function from running
  this.slug = slug(;
  // TODO make more resiliant so slugs are unique.

Day 3 | 8-30-2018:

Note: Signed employment contracts & did several interviews last calendar day 8-29-2018. Still on track for coding 301 days out of 365 😃

Day 2 | 8-28-2018:

Going through Wes Bos’s Node.js course for a quick refreasher. Killer course; I’m sure I’ll pick up some things I missed last time.


  1. Installed latest version of node form the node.js website.
  2. Created a database in Mlab.
  3. Checked Node version Node -v.
  4. Created and move to working directory \301DaysOfCode\Day-1-Node-JS-Practice\starter-files.
  5. Ran Node install on package.json dependencies.
  6. Replaced DB connection string & renamed sample environment file.
  7. Downloaded, installed and verified database connection (via connection string) with Mongo DB Compass.
  8. Ran npm start to kick start our server locally on localhost:7777.


  1. Installed JSON formatter to view JSON syntax in Chrome in a user friendly way.
  2. Echo a data string onto the page from the address bar. res.json(req.query);

Routes - Req/Res

  1. Use the req callback function to search the route’s code block for statements and logic to run.
  2. Use the res callback function to output / display info for the client/browser.

Pug(Jade) Template Engine

    p.hello Hello!
    span#yo YO!
img(src="dog.jpg" alt="Dog")
h2 Hello <br>
  em How are you?
res.render('hello', {
    name: 'was',
    dog: 'snickers'
p.hello Hello my dog's name us #{dog}"dog.jpg" alt=`Dog ${dog}`)
block header

EOD Note Got tired / spacey on the template helpers video #6. Rewatch tomorrow.

Day 1 | 8-27-2018:

Checking out Wes’s Mastering MarkDown Course. It’s 100% free and helped me fill out this journal entry.
