TypeScript 5 vs JavaScript: Choice for AI Development
Why TypeScript for AI apps? Type safety, IDE support, fewer bugs with LLM integrations.
TypeScript 5
Typed JavaScript. Inference, Zod integration, better DX. Almost standard for AI stacks (tRPC, Prisma, Vercel AI SDK).
JavaScript
Untyped. Quick prototyping, less boilerplate. More runtime bugs, less tooling.
