script tags
When exactly is a script loaded and when is it executed? How do the async and defer attributes affect it? What about modules? This overview/cheatsheet sums it up nicely: The cheatsheet was extracted from this tweet by Addy Osmani
Nice post comparing these three approaches and detailing why you should use the version with hooks. // #1 – Hooks const MyComponent = () => { const mousePosition = useMouse(); // mousePosition.x, mousePosition.y } // #2 – Render Props const MyComponent = () => { return ( <Mouse> {({ x, y }) => { // …

Recently I was invited as a speaker to Full Stack Ghent and PHP-WVL. At both events I brought a new talk called “Going Serverless with Google Cloud Run”. Cloud Run is a fully managed compute platform by Google that automatically scales stateless containers. By abstracting away all infrastructure management, us developers can focus on what …
useDeepCompareEffect Hook: A useEffect using deep comparison
A custom Hook by Kent C. Dodds (who else?) that might come in handy for “those situations”: React’s built-in useEffect hook has a second argument called the “dependencies array” and it allows you to optimize when React will call your effect callback. React will do a comparison between each of the values (via Object.is) to …

I like this review of the Mac Pro by The Verge. Very nuanced, something you don’t come by often these days. In short: It’s a hell of a machine which costs a ton. Adobe’s software is not taking advantage of all of the machine’s power. The XDR Display might or might not work for you. …
Late January Puppeteer 2.1.0 got released, with native support for Firefox: The launcher now has an option to run Puppeteer with different browsers, starting with Firefox. Puppeteer can now talk to a real, unpatched Firefox binary. This is a first step towards eventually deprecating the separate puppeteer-firefox package in favor of supporting Firefox directly in …

Intl.DisplayNames
An ECMAScript Internationalization API Feature that currently is in Stage-3 and that has already landed in V8 version 8.1 is Intl.DisplayNames.
