JavaScript

I enjoyed this blog post from Blake Watson about a simple requirement and then going down the rabbit hole of functional programming to solve it in increasingly reusable, if mind-bending ways. By the end: Creating a function that returns a function that returns a function can get a little trippy to think about. But what […]

Allen Pike “after about a decade away from regularly writing JavaScript” comes back to take a look. I think these points are all correct: The goal was to see if there was an obvious (boring, trodden) framework, and the answer is… kinda?

There are quite a few tools to avoid *needing* a database these days, static site generators chief among them. So then what are the things that push toward or require a database?

I can imagine being asked at an interview: What’s the difference between JavaScript engines and JavaScript runtimes? Nicholas C. Zakas says: A JavaScript engine implements ECMAScript as defined by the ECMA-262 standard. ECMA-262 defines the core functionality of JavaScript without any affordances for input or output. A JavaScript runtime is an ECMAScript host that embeds […]

How many ways are there to add an event (like a click) to an element? Andrea Giammarchi covers them. The first two are basically the same (hence the “2.5” in the title). I’d say the vast majority of event handling is through addEventListener, but the clearly listed advantages/disadvantages Andrea goes through are worth understanding. The […]

Pretty interesting trickery here, encoding a secret message in an emoji that you automatically get when you copy/paste it from Paul Butler. Most unicode characters do not have variations associated with them. Since unicode is an evolving standard and aims to be future-compatible, variation selectors are supposed to be preserved during transformations, even if their […]

For who-knows-what reason color inputs only show a color swatch, not a string representation of the color. Let’s see if we can fix that.

The typical approach for these inputs is using multiple HTML inputs, one for each character. But is that a good idea?

Leaflet.js is a free open-source mapping library. We’ll look at how to use it to create a basic map with location points of cats up for adoption.

This helps load in data just *before* a user gets to it, and it works with non-root containers and horizontal scrolling.
