## Resource

Lucas and Luna explore how TypeScript has grown from a niche superset to the default language for large-scale JavaScript development in 2026. They break down the recent milestone of 70% adoption among professional developers, the impact of the TypeScript 5.8 release with its new decorator standard, and why companies like Vercel and Google are investing heavily in the ecosystem. The episode also covers the rise of TypeScript-first frameworks like Deno and Bun, and the ongoing debate about whether TypeScript is becoming too complex for small projects. The hosts examine a case study of a mid-size startup migrating 200,000 lines of JavaScript to TypeScript and the concrete productivity gains they achieved. #TypeScript #JavaScript #ProgrammingLanguages #WebDevelopment #Deno #Bun #Vercel #Google #TypeScript58 #Decorators #Technology #TechPodcast #SoftwareEngineering #Coding #TypeSafety #LanguageDesign #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
