Code is the kind of thing that the fewer words used to explain it, the clearer the lesson. The solution? Forget about traditional note-taking.There are two tools which are at the heart of my workflow (right next to Github and Sublime): Repl.it: Great for taking down examples of code and saving them. This not only lets […]

function shuffle(array) { for(var j, x, i = array.length; i; j = Math.floor(Math.random() * i), x = array[--i], array[i] = array[j], array[j]= x); return array; }; |
Found this incredible loop on Stack Overflow while looking for an array method to shuffle my array. I was trying to do all of the above with basic iteration, but this is an incredible find. This is my little exercise: what do these elements of the loop do?
Scope mostly refers to the use of your variables. Imagine boxes inside one another. When we’re beginning a document, we’re in the global scope. As soon as the first function is written, we’re in the Local scope. Global code cannot access local code, but local code (functions) can access global. Access works from the inside […]

var myAnimals = ["cat", "dog", "cow"]; var counter = 0; for (i = 0; i < myAnimals.length ; i++) { counter += i; } return counter; |
3 Parts to a for loop: before the loop var i = 0 , the condition for executing the loop i < myAnimals.length , and what to do when the loop finishes i++ . The loop itself is the code block passed between { }. This will be executed for as long as the condition is true.
Today was the first day of WDI at General Assembly. Mostly we covered the groundwork: how to use Git, terminal (or command line), and barebones HTML. It was definitely worth it to do the pre-work, though I’m fairly familiar with all these things currently so it wasn’t too rough. Still, it helped me get a […]
This post marks the beginning of my journey to switch career fields. I’ll be going through an immersive course for web design where I’ll be learning Ruby and Javascript. HTML and CSS are part of it, but I’ve got a rather strong foundation in those two languages to lean on. The former languages, not so […]
