The best reason to write a library in plain JavaScript is that it lasts forever. This is arguably JavaScript’s single most underrated feature. While I’m sure there are some corner cases, JavaScript from 1999 that ran in Netscape Navigator will run unaltered, alongside modern code, in Google Chrome downloaded yesterday. That is true for very few programming environments.
And yet:
Of course, most people’s experience with JavaScript is that it ages like milk. Reopen a node repository after 3 months and you’ll find that your project is mired in a flurry of security warnings, backwards-incompatible library “upgrades,” and a frontend framework whose cultural peak was the exact moment you started the project and is now widely considered tech debt.
I really like the progressive enhancement approach that this little library uses—it’s basically the Hijax approach I was talking about back in the days of Bulletproof Ajax but all wrapped up into a neat package that you can use entirely via HTML attributes.
Want to use all those great features that have been in landing in browsers over the past year or two? View transitions! Scroll-driven animations! So much more!
Well, your coding co-pilot is not going to going to be of any help.
Large language models, especially those on the scale of many of the most accessible, popular hosted options, take humongous datasets and long periods to train. By the time everything has been scraped and a dataset has been built, the set is on some level already obsolete. Then, before a model can reach the hands of consumers, time must be taken to train and evaluate it, and then even more to finally deploy it.
Once it has finally released, it usually remains stagnant in terms of having its knowledge updated. This creates an AI knowledge gap. A period between the present and AI’s training cutoff. This gap creates a time between when a new technology emerges and when AI systems can effectively support user needs regarding its adoption, meaning that models will not be able to service users requesting assistance with new technologies, thus disincentivising their use.
So we get this instead:
I’ve anecdotally noticed that many AI tools have a ‘preference’ for React and Tailwind when asked to tackle a web-based task, or even to create any app involving an interface at all.
Anselm isn’t talking about becoming a CSS wizard, but simply having an understanding of what CSS can do. I have had similar experiences to this:
In the past years I had various situations where TypeScript developers (they called themselves) approached me and asked whether I could help them out with CSS. I expected to solve a complex problem but for me — knowing CSS very well — it was always a simple, straightforward solution or code snippet.
Let’s face it, “full stack” usually means “JavaScript”—HTML and CSS aren’t considered worthy of consideration. Their loss.
Debating complexity is pointless because it’s a subjective metric. Every developer has a different gut feeling about simplicity, complexity and the appropriate amount of complexity for a given task. When people try to find an objective definition, they come to wildly different results. And that’s okay.
Instead, we should focus on hard metrics from a user perspective. Performance, efficiency, compatibility, accessibility and fault-tolerance can be measured, tested and evaluated, automatically and manually.
Any amount of complexity is fine as long as these goals are met.
Since the early days of the web, large corporations have seemingly always wanted more than the web platform or web standards could offer at any given moment. Whether they were aiming for cross-platform-compatibility, more advanced capabilities, or just to be the one runtime/framework/language to rule them all, there’s always been a company that believes they can “fix” it or “own” it.
Applets. ActiveX. Flash. Flex. Silverlight. Angular. React.
Don’t replace. Augment.
Two JavaScript frameworks—Svelte and Astro—share a philosophy, but take subtly different approaches.
Materials and tools; client and server; declarative and imperative; inclusion and privilege.
Why I get more excited about new CSS features and JavaScript APIs than I do about new frameworks, libraries, or build tools.
Balancing the ledger.
