Resources to Level Up
Fireship
100-second explainers that somehow teach you more than a 3-hour course. Jeff's production quality is insane and the pacing keeps you locked in.
30 Seconds of Code
Bite-sized JavaScript (and other languages) snippets you can actually use. Great for filling gaps in your knowledge or finding a pattern you half-remember.
TypeScript Deep Dive
A free open-source book that bridges the gap between the official docs and real-world TypeScript. No nonsense, very practical.
freeCodeCamp
Thousands of hours of free curriculum, certifications, and projects. The JavaScript algorithms section alone is worth bookmarking.
TypeScript Handbook
The official TypeScript docs, written by the team that built it. Covers everything from basic types to mapped types and template literal wizardry.
TypeScript Playground
Official browser-based TypeScript sandbox. Test types, share snippets, explore how TS compiles. More useful than it sounds.
Zustand Docs
State management without the ceremony. Zustand's docs are minimal because the API is minimal, in a good way.
type-challenges
A GitHub repo full of TypeScript type challenges sorted by difficulty. These will hurt your brain in a productive way.
React Docs
The new React docs (react.dev) are genuinely great, interactive, modern, and don't assume you already know React. A complete rewrite done right.
TanStack Query
Formerly React Query. Server state management that makes data fetching, caching, and syncing feel obvious. Docs include solid patterns and migration guides.
Remix Docs
React framework built around web fundamentals, forms, loaders, progressive enhancement. Great alternative to Next.js with a different set of tradeoffs.
Next.js Docs
React's most popular production framework. App Router, server components, API routes, edge functions, all documented by Vercel and kept current.
LeetCode
The standard platform for practicing algorithmic problems. If you're prepping for technical interviews, you'll end up here, better to come voluntarily.
Framer Motion
The animation library React developers actually enjoy using. Great docs with live examples that show you exactly what each prop does.
LangChain Docs
Framework for building LLM-powered applications. Covers chains, agents, RAG pipelines, and tool integrations, the ecosystem is large and the docs keep up.
roadmap.sh
Community-driven roadmaps for frontend, backend, DevOps, and more. Useful for identifying gaps in your knowledge and figuring out what to learn next.
