Dacht je dat je bij Shell Recharge @NewMotion met je credit card kunt betalen? Nope. Als je niet van te voren een laadpas hebt aangevraagd heb je pech.
Waarom gaan we zo ver terug in de tijd?

There is even more here, but this were the things I found most interesting!
👒 Hats off to the TypeScript team for this one! Can't wait to test these out on my production code.
Of course, no release of TypeScript would be complete without improved type magic by @ahejlsberg 🧙♂️. This time in the form of better inferring the types of objects with methods.
The goal here is to be able to write JS that "Just works" without worrying about the type checker 🤗

In TS 4.7 it is possible to declare a type alias for generic types where _some (or all) of the generic types are filled in already_. This is a small but useful improvement. This feature is called "Instantiation Expressions"

TS 4.7 brings explicit variance syntax using `in` and `out` in a generic type declaration 🗯. Co- and contra-variance has been supported ever since `--strictFunctionTypes` was introduced, but there was no way to be explicit about it. Now there is!

TS 4.7 comes with much-needed improvements to ECMAScript module (ESM) support for Node.js 📦. This will accelerate ESM adoption for the entire Node.js ecosystem. Almost every utility library and development tool will be helped with these features.

I have converted dozens of projects to TypeScript at this point, and in *every single one* there have been multiple bugs found as a result.
Every! Single! One!

I needed this today! A positive sound about the climate crisis. Avoid doomerism! @Kurz_Gesagt

Are Hot vs. Cold observables still a thing in #rxjs? Nothing seems to be on the official rxjs.dev website about it and I can only find an old blog article by @BenLesh

Can we create an ecosystem for type artists? I've put together an RFC to explore what's possible and kickstart the discussion around this!

Today, I'm proud to announce my ECMAScript proposal: comments as types 🎉 (Stage 0 as of now).
github.com/nicojs/proposal-c…
This counters @giltayar 's original "Types as comments" proposal but solves all the obvious problems with it.

Any #rxjs experts out there that can take this one? stackoverflow.com/questions/…
It turned out I could ignore parts of it I didn't like. Now rolling my own with TS compiler in watch mode and nodemon 😎.
What will happen with the framework now that decorators are stage 3 is the biggest question I have 🧐
I've been working on a #nestjs app recently and I've got to say I love the experience. Especially the comprehensive guides 😍. Adding ORM and authentication is a breeze 💨. Just wish they were a bit less opinionated in the TS setup department 🤷♂️
