What this episode covers

Neue TypeScript-Version, Stefan und Peter, Abschweifen. Ihr kennt das Spiel. JSCRAFTCAMP Das JSCraftCamp ist eine zweitägige Unkonferenz, bei der es um Software-Crafting von JavaScript-getriebener Software geht. Hier könnt Ihr nicht nur Euer Sprachverständnis gemeinsam mit anderen aufbauen oder schärfen, es können auch Programmierpattern, Frameworks oder Transpiler Themen für Sessions sein. Da es sich um eine Unkonferenz handelt, gestaltet Ihr alle das Programm zusammen, nach Euren Wünschen! Wann: Am 30. Juni und 1. Juli 2023 Wo: codecentric, August-Everding-Str. 20, 81671 München Alle Infos unter jscraftcamp.org. SCHAUNOTIZEN [00:01:27] TYPESCRIPT 5.1 Bevor wir uns in die neuen Features von TS5.1 stürzen, blicken wir zurück auf die in Revision 560 besprochene Version 5.0 und überlegen, warum sich bisher (die nun ja auch in ECMAScript standardisierten) Decorators nicht weiter durchgesetzt haben – Schwenks zu Yehuda Katz und Ember bzw. Glimmer inklusive. An der Feature-Front beginnt der Abbau der Unterschiede zwischen void (nicht zu verwechseln mit void, siehe Stefans Artikel zum Thema) und undefined, was wir begrüßen. Ebenfalls aufgeweicht werden die Anforderungen an die Typen von Getter and Setter-Signaturen, v.a. um Legacy-Use-Cases rund um Stylesheets (jenseits von Constructable Stylesheets) zu bedienen. Anlässlich diverser Anpassungen der JSX-Typen (u.a. für mögliche zukünftige Promise-Komponenten in React) waschen wir ein wenig React-Schmutzwäsche und feiern und besprechen die Genese des Dynatrace App Toolkit. Da uns zu den weiteren Kleinigkeiten nicht ganz so viel einfällt, verlegen wir uns zum Ende hin auf Werbung! Peter empfiehlt eine VS-Code-Extension für schönere TypeScript-Fehlermeldungen und hat einen Text zu unknown-Overloads geschrieben, wohingegen Stefan gleich ein ganzes zweites Buch zu TypeScript zur Papier gebracht hat.
