Complete Intro to React, v9 vs Introduction to Next.js, v3

The course covers React 19 from initial project scaffolding with Vite through hooks (useState, useEffect, useContext, useReducer), component composition, routing with TanStack Router, and performance patterns — all organized around building a production- style e-commerce application rather than isolated toy examples. Reviewers consistently praise the modern toolchain (no Create React App), the focus on current patterns that actually work in production codebases, and the absence of outdated class-component material. The v9 designation signals genuine curriculum updates rather than cosmetic refreshes, which is rare among multi-version React courses.

Brian Holt is described across all reviewed sources as an exceptional teacher — specifically praised for making complex concepts feel obvious through clear analogies, methodical build-up, and a conversational delivery that stays engaging across eight hours of video. Multiple reviewers note that experienced React developers still learn meaningful things from Holt's explanations, suggesting depth beyond what the beginner framing implies. He is repeatedly described as a GEM among Frontend Masters instructors.

The course requires a Frontend Masters subscription ($39/month or $390/year), which gives access to the full course catalogue of 200+ expert-level courses — not a single-course purchase. For developers who intend to use more than a few courses, the subscription offers strong value. For learners who only want this one course, the subscription model is a higher upfront cost than a typical Udemy purchase. Frontend Masters does not offer a permanent free tier, though the course notes and exercises are publicly accessible at react-v9.holt.courses.

The e-commerce project format means learners build a real application rather than disconnected code snippets, and the toolchain — Vite, ESLint, Prettier, TanStack — mirrors what professional React teams actually use. Reviewers who moved directly from the course to their first React role or freelance project report that the patterns transferred immediately. The course avoids outdated approaches that would confuse learners encountering a modern codebase, which sets it apart from older React curricula still teaching class components as the primary pattern.

Building a complete e-commerce application — covering product listings, a shopping cart, routing, and state management — gives learners a deployable project and a portfolio piece, not just completed exercises. Reviewers highlight that the project scope is substantial enough to demonstrate real React understanding without being overwhelming. The course's companion notes at react-v9.holt.courses also let learners self-pace the text-based curriculum independently of the video playback speed.

The course targets Next.js 13+ and is built around the App Router, covering file-based routing, layouts, route groups, React Server Components, server actions, and Prisma-backed data persistence. Learners consistently praise its production-focused selection of topics — Scott Moss explicitly states he only teaches what he uses in production, which keeps the material lean and relevant. The companion GitHub repository (130+ stars, 66 forks) with branch-per-lesson structure is repeatedly cited as a standout resource for quick lookups. A meaningful minority note that the course deliberately omits several Next.js features (useRouter, usePathname, intercepting routes, advanced image optimisation) and that the v3 content has been partially superseded by Next.js 14/15 changes to caching and the dynamicIO model — though older versions remain accessible on the platform.

Scott Moss is a senior software engineer at Netflix and a two-time Y Combinator founder, which gives his production-first framing credibility. Learner feedback across multiple sources consistently uses superlatives: "incredible," "remarkably well-spoken," "complex concepts broken down into clear, manageable steps." Jason Lengstorf of Learn with Jason called him "one of the best teachers out there." Frontend Masters founder Marc Grabanski credits Moss with convincing the platform to keep releasing updated Next.js course versions as the framework evolved. The only instructor criticism that surfaces is that the pace is too brisk for developers who are still consolidating React fundamentals.

Access requires a Frontend Masters subscription at $39/month or $390/year (~$32.50/month). Against that cost, this single course runs roughly 4-5 hours of video, which makes the monthly plan the appropriate entry point for first-timers. The value equation improves substantially when the subscription unlocks the full library: the React & Next.js learning path alone is listed at 40+ hours across seven courses. Multiple long-term subscribers report renewing two to three times per year and consider the ROI immeasurable relative to skill gains. The course notes and GitHub branches are freely accessible without a paid account, offering a partial free tier for budget-constrained learners.

The build-along project is a SaaS-style notes application backed by Prisma and a database, described as "ready for funding" in the course companion site. The project is realistic enough to demonstrate authentication flows, server actions, and data persistence in a single coherent app. However, reviewers who compare it to full-length bootcamp alternatives note that the final deliverable is relatively modest in scope — closer to a polished proof-of-concept than a portfolio centrepiece. The branch-based Git workflow (one branch per lesson with working solutions) is consistently praised as a learning aid, making it easy to recover from dead-ends without rewatching video.

The consistent theme across learner signals is that Scott Moss's production background at Netflix and Y Combinator-backed startups shapes every topic choice. The course prioritises patterns developers actually encounter — form authentication, server-side data fetching, middleware, and Vercel deployment — over exhaustive API coverage. Several learners note that after completing the course they felt confident starting a real Next.js project rather than needing another tutorial. The primary caveat is framework velocity: App Router and server actions have evolved since the v3 recording, and learners working on Next.js 14+ projects may encounter API-level differences that require cross-referencing the official docs.
