JavaScript Weekly Issue 602: August 12, 2022

☀️ We’re taking a rare week off next week for a brief summer vacation so there won’t be any issue on August 19 – we’ll be back on August 26, complete with a sun tan wind burn, and all the latest JavaScript news, of course 🙂

Astro 1.0: The Fast Islands-Based Frontend Framework — Despite its relative youth, Astro has had a big impact already with a wide range of users and support for, well, almost every other framework or dev tool going. It’s based around ‘islands’ where fast HTML can stand in for components which can then be lazily loaded in as user interactions demand. 1.0 introduces new image and picture components, MDX/Markdown support, and SSR builds. There’s a new homepage too.

Fred Schott Modern Web App Design Patterns — A free book you can download in PDF format or enjoy on the Web. Learn about lots of fundamentals, from how different styles of rendering or importing resources work to performance optimizations and case studies. There’s a lot to enjoy and a fantastic team behind it, too.

If you’ve got a few minutes, ▶️ this video of a recent winning ‘demo’ from a demoscene contest is pretty mindblowing.

The code was written in 2022, but is running on a 1981 IBM PC using CGA graphics and if you’re old enough to have used such a machine (like me!) it’s amazing what they’ve managed to squeeze out of it. As one commenter (Jeff Haluska) said: “I have been programming for about 25 years and Area 5150 has me questioning everything I know about computers.”
