The `class` syntax of #JavaScript is getter more and more similar to #Java. Previously instance / static class fields were already added. And now the upcoming JavaScript will also support "static" initialization blocks. For more information read the blog post below of 2ality blog (INACTIVE)

Tip: you can use Object.is instead of triple equal to get expected behavior for equality checks of NaN values and +/- 0.

So happy to be living in European Union where General Data Protection Regulation (#GDPR) legislation prohibits leaking of personal data like social security numbers. Really the world turned up-side down... to prosecute someone who reported the personal data being leaked.

Just finished my new blog post of Divotion about Yalc, an interesting alternative to using `npm link` (or `yarn link`). Yalc offers a nice middle ground between npm link and installing npm pack-ed .tgz files, and also works when `npm link` does not. divotion.com/blog/yalc-npm-…

🧵 The Ultimate TypeScript Thread 🧵 Here's everything I've learned from leading TS dev teams and working on XState's core team. My goal is to turn you into a TypeScript wizard. And yes, this thread is EVERGREEN - I'll add at least 3 more tips a week 🚀 Let's get started.

⚠️ In #React v18 there is a breaking change in its #TypeScript typings. The `children` prop is no longer implicit for `React.FC`... and will have to be added explicitly. More info in the original tweet below 👇 , and see follow-up tweet for automatic code migration tool.

As of #Redux v. 4.2.0 the `createStore` function is marked deprecated (through JSDoc). Instead one should instead use the `configureStore` function of the #ReduxToolKit (RTK).

David Wells Justin Fagnani To understand `useEffect` in #React requires a total different mental model. Hooks are all about synchronization and not about lifecycle. IMO, to fully comprehend `useEffect`, the following article of dan_abramov is a definitive must read: overreacted.io/a-complete-gui…

Adarsh Gupta ✨ Kent C. Dodds ⚡ Personally I have this utopian dream to 100% #UseThePlatform for building complex web apps. Even though we aren't quite there yet, one could still be near-vanilla by using only small supplementary libs like Lit (Lit) or a code generator like #StencilJS or #Svelte.

IMO, one of the best features of #TypeScript is its automatic type narrowing (e.g. if-statement with typeof) often making explicit type assertions (casts) unnecessary. The article below 👇 describes how automatic type narrowing can also be done for Array methods filter and find.

Instead of using the #Axios #JavaScript lib, one could also consider Redaxios, that (only) uses the built-in browser #FetchAPI under the hood. Redaxios is a drop-in replacement of #Axios, but is only 1/5 the size and is developed by Jason Miller 🦊⚛ who's the author of #PreactJS

Vanuit #Divotion verzorgt Emil van Galen op #FortX een echte #frontend talk: ‘#TypeScript Yin-Yang - why it's just #JavaScript, but with seat belts fastened’. Wat zijn de verschillen en overeenkomsten tussen TypeScript en JavaScript? Koop nu je kaartje voor Fort X.

Ik zie er erg naar uit om te spreken spreken op de jubileumconferentie Fort-X. JDriven collega Sander Smeman en ik waren op 1 april 2011 de allereerste medewerkers en sindsdien is JDriven enorm gegroeid en zijn er spin-offs ontstaan waaronder Divotion.
