Should web developers and JavaScript library authors still transpile their code to ES5? This post looks at what the data suggests based on what popular libraries, tools, and websites are doing

Thoughts on web development, open source, software architecture, and the future.

The “Promises” API is a surprisingly tricky part of modern JavaScript. Without the right context, it doesn’t make much sense at all! In this tutorial, you’ll build an intuition for how Promises work by getting a deeper understanding of JavaScript and its limitations.

Have you heard of the Screen Orientation API? What about the Device Orientation API, Vibration API, or the Contact Picker API? Juan Diego Rodriguez is interested in these under-the-radar web features and discusses how they can be used to create more usable and robust progressive web apps if and when they gain broader support.

An arrow function expression is a compact alternative to a traditional function expression, with some semantic differences and deliberate limitations in usage:

When I think of showing off syntax highlighted code on the web, I think of code that takes in a string of code, finds relevant substrings (tokens) with elaborate RegExes, then wraps them in spa…

I’m working on a new project-based JavaScript course for beginners and aspiring developers. In addition to a ton of projects, I wanted to include little mini-challenges with each lesson. And to do that, I want to include a code sandbox (like CodePen) right in the tutorial. Rather than loading buckets of React like most libraries for this require, I decided to build my own. Let’s look at how! An example challenge For example, imagine that you’ve just learned about the Array.

Thanks for watching to me chat with Kevin about JavaScript and more! I’ve put together a ton of resources to help you dig deeper into building simpler, more resilient web experiences.

Let's say you don't know JavaScript. You're a web designer and you're focused largely on UI and UX. Let's look at some things you could learn in a day that will give you that bang for the buck.

There are two main paradigms in programming: imperative and declarative. Every other paradigm, such as reactive, functional, and procedural, is just a subset of one of these two. Often, you hear that declarative code is better than imperative code an...

An array is like a queue where you can have zero, one or many values. The first value can be found at index 0, and others follow. An empty array, like a queue with no one in it, is written in JavaScript as `[]`. The `[` and `]` are the start and end markers, and items inside are separated by commas.For example, to make an array with the numbers 0 to 3, you write `[0, 1, 2, 3]`.

Runtimes and engines are often incorrectly referred to as the same thing.

In the ever-evolving landscape of web development, the need for scalable, maintainable, and flexible...
