ES6 Modules

ES6 modules allows us to have reusable code, in separate files. We do this to eliminate initially massive js files, like app.js in a Node and Express project. Modules allow us to spread code over relevant files. Take this students.js file const students = [‘Peter’, ‘Paul’, ‘Mary’]; export const

DRY Code: Using IIFEs to Clean Up Code

DRY: Don’t Repeat YourselfAs you may have seen in my last post, I have some ridiculous conditional statement blocks going on to show/hide the Skycons and for switching up the background photos based on your current weather conditions. Each of this if/else statements is essentially repeating the

Gauging My Progress

As I step through The Web Developer Bootcamp, I am beginning to realize just how much I’ve learned the last two years and how it is beginning to codify in my brain. I am coming from a Humanities background but I have always had technical chops, working with circuits

Working With Arrays Part 2

What is an array? You use an array to store data. You can initialize an empty array and then store data in it as well. But that is beyond the scope of this post. There are 4 types of arrays in JavaScript: HomogeneousHeterogeneousMultidimensionalJagged (or ragged)Homogeneous ArraysHomogeneous arrays only store

Working With Arrays, Part 1

This will be a series on working with arrays. Not sure how long it will be but there is so much rich information about arrays in JavaScript that I don’t think I could fit it all into one post. It may not be a series after all; I may

The Execution Stack and Scope

What is the Execution Stack? Before I answer that question, we’ll first have to take a look at the Global Execution Context The Global Execution Context, in general terms, is the environment in which the function gets invoked, or the variable’s scope. The Global Execution Context, creates global

Scope for Beginners

In JavaScript, lexical scope deals with where your variables are defined, and how they will be accessible — or not accessible — to the rest of your code. There are two terms to think about when talking about scope: local and global. These two terms are important to understand, because one can

Primitive Data Types in Java

Variables in Java need to be declared before they can be used in Java because it is a statically-typed language. Because of this, you need to state the type of variable you are declaring. A variable’s data type tells Java what type of data the variable contains. For instance,

Objects and JSON

What are JavaScript Objects?When thinking about JavaScript objects, it is important to think about them in terms of real life objects. For instance, you have a cup, which is an object. The object has some properties: it is white, it has some text, it is holds 12 oz, it

Let and Const for Block Scope

Up until ES6, you couldn’t achieve true block scoping in JavaScript. With the var keyword, the scope in a code block could be accessed in the global scope, as variable declarations are hoisted to the top of scope and the assignments are kept where they are. For instance, take
