What this episode covers

Am späten Abend eines langen Tages trafen sich Stefan und Peter, um traditionell die Verheißungen der neuesten TypeScript-Version zu interpretieren SCHAUNOTIZEN [00:00:30] TYPESCRIPT 4.1 (BETA) Die Liste der neuen Features beginnt mit Template Literal Types (vgl. Template Literals in JS) sowie rekursiven Conditionals. Daraus resultieren allerlei beeindruckende Tech-Demos wie etwa ein CSS-Selektor-Lexer, eine SQL-Engine und ein Rechtschreibprüfer – alles implementiert als TypeScript-Typ! Den Sinn und/oder Unsinn solcher Features diskutieren wir ebenso in epischer Breite wie die Entstehung und Konzeption von Stefans TypeScript-Buch, die Performance des TS-Compilers (nebst Tools wie Webpack und Vite), React, Preact, Promises, type-challenges und Private Class Fields in TS. Schreibt gerne einen Kommentar, wenn ihr wisst, was es mit den JSX-Factories in React 17 auf sich hat! [00:00:00] KEINE SCHAUNOTIZEN STEFANS TYPESCRIPT-BUCH „TYPESCRIPT IN 50 LESSONS“ Kauft Stefans Buch! Es ist sehr gut!
