As of ES6, we are able to set default parameter values when defining a function, as shown below: This allows for named parameters to be initialized with default values if no value is present or it evaluates to undefined.

Node.js is a perfect runtime to create a CLI script that can run on any machine that has Node installed. A CLI program in Node is really just an ordinary Node.js app. In order to make the program available to be executed by your machine, we need to do a couple of small setup steps. […]

When debugging in JavaScript, browser extenstions can be a potential source of confusion. At the very least, they may add additional noise to the process. In order to make sure you’re not dealing with any extra code outside of your application, you can use Incognito Mode to browse in private. This disables all of your extensions […]

Object-Oriented Programming (OOP) is a popular programming paradigm that allows us a way to structure and maintain complex code. Unlike other programming languages that use class-based object orientation, JavaScript uses prototype-based object orientation. This difference may be a source of confustion for developers coming from a class-based language, especially when using the “syntactical sugar” of […]

New with ES6, we have an additional way to write function expressions in our code – as arrow functions. This new syntax offers 3 main benefits: They are much more concise than regular function expressions/definitions They have implicit returns, which allow us to write single-line expressions (much like we can do with conditionals and the […]

As of ES6, we have two new ways to define variables, in addition to the classic var keyword. Each are a little bit different in their own way and I’ll break down those differences in this article.

Up until somewhat recently, saving the state of the application locally in the browser via Cookies was the main way to achieve this. Cookies have limitations, however. For example, their max […]

Recently I’ve been digging into React.js. Some my awesome co-workers are experimenting and utilizing the library in some pretty cool ways, so it really sparked my interest. As a result, I’ve collected a little list of bookmarks that I thought was worth sharing.
