Source: https://scrimbaguide.tech/docs/courses/react/ Last updated: 2026-09-28 Scrimba's React track has ten courses, from a 41-minute interview crash course to the 18.8-hour [Advanced React](https://scrimbaguide.tech/docs/courses/react/advanced-react/), running from a free, project-heavy flagship to advanced patterns, routing, testing, and interview prep. Every course is interactive: you pause the lesson and edit the code in the same browser tab. Reviewed inside the courses with a Pro account, September 2026. ## Where to start Start with the free [Learn React](https://scrimbaguide.tech/docs/courses/react/learn-react/) (15.1 hrs). It covers components, props, state, hooks, and finishes on two portfolio projects. It is the anchor for everything else in this category, so do it first whether or not you ever pay for Pro. **[Start Learn React for free](https://scrimba.com/learn-react-c0e?via=u42d4986)** ## All React courses | Course | Level | Access | Length | | --- | --- | --- | --- | | [Learn React](https://scrimbaguide.tech/docs/courses/react/learn-react/) | Intermediate | Free | 15.1 hrs | | [Learn Class Components in React](https://scrimbaguide.tech/docs/courses/react/class-components-in-react/) | Intermediate | Pro | 1.3 hrs | | [Learn React Router](https://scrimbaguide.tech/docs/courses/react/react-router/) | Intermediate | Pro | 9.7 hrs | | [Build a React Project: Movie Search App](https://scrimbaguide.tech/docs/courses/react/a-react-project-movie-search-app/) | Intermediate | Pro | 57 min | | [Build a Memory Game in React](https://scrimbaguide.tech/docs/courses/react/memory-game-in-react/) | Intermediate | Pro | 4.4 hrs | | [React Challenges](https://scrimbaguide.tech/docs/courses/react/react-challenges/) | Intermediate | Pro | 9.8 hrs | | [Testing in React](https://scrimbaguide.tech/docs/courses/react/testing-in-react/) | Intermediate | Pro | 56 min | | [React Interview Questions](https://scrimbaguide.tech/docs/courses/react/react-interview-questions/) | Intermediate | Pro | 41 min | | [Advanced React](https://scrimbaguide.tech/docs/courses/react/advanced-react/) | Advanced | Pro | 18.8 hrs | | [What's New in React 19?](https://scrimbaguide.tech/docs/courses/react/whats-new-in-react-19/) | Advanced | Free | 1.2 hrs | [Best React Courses and Tutorials Compared](https://scrimbaguide.tech/docs/courses/react/best-react-courses-and-tutorials/) compares the options above if you want a picker. ## Inside the courses ![Learn React section 3 card, Chef Claude, the recipe app that calls the Claude API](https://scrimbaguide.tech/img/scrimba/learn-react/chapter-03-chef-claude-title-card.webp) *Free carries every section of Learn React, including this Chef Claude build in section 3.

Once those land, use [React Challenges](https://scrimbaguide.tech/docs/courses/react/react-challenges/) for reps, [Testing in React](https://scrimbaguide.tech/docs/courses/react/testing-in-react/) to put tests on the app you already built, and [React Interview Questions](https://scrimbaguide.tech/docs/courses/react/react-interview-questions/) when interviews are near. [What's New in React 19?](https://scrimbaguide.tech/docs/courses/react/whats-new-in-react-19/) is a short update tour for people already comfortable with React 18; for what shipped since, see our [React 19.3 update tracker](https://scrimbaguide.tech/blog/react-updates-for-learners/). ## Where it fits React sits inside two career tracks on Scrimba Pro. The [Frontend Developer Path](https://scrimbaguide.tech/docs/paths/frontend-developer-path/) wraps Learn React and Advanced React into a longer HTML, CSS, and JS sequence. The [Fullstack Developer Path](https://scrimbaguide.tech/docs/paths/fullstack-developer-path/) adds TypeScript, Node, Express, and Next.js after React. Once you have React down, [the best Next.js courses of 2026](https://scrimbaguide.tech/blog/best-nextjs-courses/) rounds up where to go next, on Scrimba and elsewhere.
