JavaScript

You could design something on the web then take a screenshot of it. That is, in a basic sense, converting DOM to PNG. But a screenshot is rather manual and finicky. If you had to do this over and over, or you needed a very exact size (like a social media card), you can actually […]

An awful lot of JavaScript developers I know speak of Eloquent JavaScript as a very formative book for them in their path toward becoming the developer they are today. It’s certainly on my bookshelf. Eloquent JavaScript is now in it’s 4th edition, and available free online. Pretty sweet complementary learning resource right there, goes nicely […]

We left off in a decent place, but there was some missing functionality that we wanted all along. Editing To-Dos The interaction we decided on for editing is to double-click the todo. This will turn the to-do, in place, into an editable input. Then you hit enter (e.g. submit) or leave the input (e.g. blur) […]

I’m already a little over all the green. What was I thinking? I’m much more of a nice gray color palette kinda guy with some fun poppy colors. That’s what we need to get to here. When we left off, we just had wireframes going. It’s time to get some style on this thing! Custom […]

Quizzing has always been a highly requested feature, and we wanted it not just to be a test — but a course that combines challenging questions with in-depth, quality instruction. We released our first quiz-based course last year covering advanced web development topics and folks seem to really enjoy it. Today, we’re excited to release […]

Deno is getting in on the package registry business with JSR (“JavaScript Registry”). The name should help people understand it’s not Deno-specific, but instead built to support the ever-growing number of JavaScript runtimes. There isn’t much public information (it’s waitlisted), but David Bushell was able to take it for a spin.

We left off with a wireframe-y looking HTML-ized version of our design. Personally, I’m a little tempted to get some CSS on there, but let’s hold off and do the very basic JavaScript functionality first. That will make it, ya know, actually functional, and having some of the interactive stuff in place might inform some […]

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 <span>s with classes to that color can be applied to those classes. This is quite literally how it works. The really […]

URL, which stands for Uniform Resource Locator, is an address to access resources on the internet. Each URL points to a unique resource on the web. URLs can sometimes contain special characters or need to be manipulated dynamically. In this article, we’ll explore the modern techniques for working with URLs in JavaScript, and answer the […]

The <dialog> element in HTML is tremendous. We’ve got support across the board now, so using it is a smart plan. Just with basic usage, you get a centered modal dialog experience that comes up when you call it, a dimmed background, focus trapped within it, closes with the ESC key, and focus returning where […]
