Complete Intro to React, v9 vs The Web Developer Bootcamp 2024

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(no Create React App), the focus on current patterns that actually work in production codebases, and the absence of outdated class-component material.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 The course avoids outdated approaches that would confuse learners encountering a modern codebase, which sets it apart from older React curricula still teaching class components as the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.

Broad full-stack scope (HTML, CSS, JS, DOM, Node, Express, MongoDB) that shows beginners the whole shape of a web app. One recurring 2024 critique flags Udemy paid courses for "low effort updates" vs MDN or Odin.

Strongest criterion. Long-time HN users name Colt their "favorite web dev teacher" and credit his in-person classroom background. Signature move is walking students directly into mistakes then guiding them out.

Listed near $200 but routinely buyable for $10-$20 in Udemy sales — a price every commenter we tracked considers a giveaway given the runtime and lifetime access. The standard advice is to clear cookies, use incognito, and never pay sticker.

The build-along YelpCamp full-stack project (Express + MongoDB + authentication + image uploads) is the most-cited reason people finish the course feeling they built something real. Smaller mid- course exercises are praised as friction-removing but less portfolio-defensible.

Strong fundamentals on HTML, CSS, vanilla JS and a basic Node/Express/Mongo stack that transfers to most web roles. Weaker on modern tooling, TypeScript and React — most learners take a follow-up framework course to close the gap to a 2026 front-end job.
