Sep 15 · Day 6

MINOR · GPT · QUESTION 31

GPT went back to its usual response time on a question about which JavaScript framework to start with.

Why it’s minor

The change lasted one day before the model went back.

The full answers

Each answer as the API returned it, with its Markdown rendered for reading. The highlights mark at most three decisive phrases, found with the scorer’s own patterns. Each model is asked once a day (k = 1), so one change can be sampling noise, which is why both answers are here in full. How scoring works.

Asked verbatim · Question 31

Which JavaScript framework should I start a new project with today?

SEP 14the changePermalink

With no other context, start with TypeScript + React.

Choose the setup based on the project:

  • •Next.js — best general default for a production web app needing routing, server rendering, SEO, authentication, or backend endpoints.
  • •React + Vite — better for a client-side SPA, internal dashboard, or app with a separate backend.
  • •Vue + Nuxt — choose if you value a gentler learning curve and cohesive developer experience.
  • •SvelteKit — excellent for small teams prioritizing simplicity and performance, with a smaller ecosystem.
  • •Angular — strongest fit for large enterprise teams wanting strict conventions and an all-in-one framework.

My practical default:

Public/full-stack product: Next.js + TypeScript
Client-only application: React + Vite + TypeScript

If you describe the project—public site vs dashboard, team size, SEO needs, and backend—I can narrow it to one choice.

SEP 15backPermalink

Default recommendation: Next.js with TypeScript—especially for a production web app needing routing, server rendering, APIs, authentication, or SEO. It has the broadest ecosystem, strong hiring market, and many deployment options.

Choose differently when:

  • •Client-only SPA: React + Vite
  • •Simpler, highly approachable stack: Vue + Nuxt
  • •Small bundles and elegant developer experience: SvelteKit
  • •Content-heavy/static site: Astro
  • •Backend/API only: Fastify or NestJS

If you have no special constraints, start with:

npx create-next-app@latest my-app --typescript

Avoid adopting extra state-management or data-fetching libraries until the project actually needs them.
