1) learned some new html today

Looking at youtube blog, https://youtube-eng.googleblog.com/2018/08/control-your-360-videos-with-youtube.html

ran into the following code:

<!--[if IE]>
  <script type="text/javascript" 
    src="https://www.blogger.com/static/v1/jsbin/1277698886-ieretrofit.js"

Everyone seems to know this, but here is a good refresher in case I ever forget.

  useEffect(() => { console.log('I am a component, 1 render') }, [true]);

Pointed empty array works you dont need true, My paranoid self thought that I read in the documentation that empty array would track all. This was not the case.

  useEffect(() => { console.log('I am a component, 1 render') }, []);

function a() { this.foo = 1;}
function b() { this.bar = 2; }
b.prototype = new a(); // b inherits from a
var f = new b();

function type(obj){
 return Object.prototype.toString.call(obj).match(/\s\w+/)[0].trim()

Today I learned, when to use:

  event.preventDefault();
  event.stopPropagation();

Ever need to have a click event on a child element trigger but not on the parent element?

Anyone use event.preventDefault on a regular basis?

Found a really good explanation with working examples on stack overflow 🎉

const alphabet = [
  'a', 'b', 'c', 'd', 'e','f','g','h','i','j','k','l','m',
  'n','o','p','q','r','s','t','u','v','w','x','y','z'
]

const deepCopyAlphabet = () => JSON.parse(JSON.stringify(alphabet));
const getRandomInt = (arr) => Math.floor((Math.random() * arr.length))

let mainGraph = []
const connectNodesByNumber = ({letter, num, arr, mainGraph, isRandom}) => {

var parentList = document.getElementsByTagName('li');
for(var x = 0; x < parentList.length; x++) {
  var childList = parentList[x].getElementsByTagName('ol')
  for(var y = 0; y < childList.length; y++) {
    childList[y].remove()
  }
}

# Elixir has lazily evaluated enumerable objects that allow you
# to work with enumerable objects like lists either only as needed
# or infinitely.

# Start up iex to play around
$ iex

# Typical enumeration is done eagerly where the result is computed ASAP
iex> Enum.map(1..10, fn i -> i * 2 end)
