A challenge-based React course built as an interactive platform rather than a video library, combining illustrated text lessons with coding challenges, quizzes and a set of custom hooks to rebuild from scratch. Ten sections run from the rendering model through custom hooks, concurrent rendering and server-side React, closing with interview questions. Sold as two lifetime packages that differ in how much is included, plus an annual subscription bundling the wider library.

Who it is for

Developers who have used React and want to understand why it behaves as it does rather than only how to use it.

Recorded from the provider’s published description of the course.

What the course covers

Summarised by TrustMyCourse from public course information. Wording is our own, not the provider’s.

  1. The Big Picture

    Where React sits and what problem it is actually solving, before any API.

  2. Describing UI

    Components and composition as a way of describing an interface declaratively.

  3. Bringing React to Life

    State and events, turning a static description into a working application.

  4. Escaping React

    Working with things React does not control, including refs and external systems.

  5. Optimizing React

    Where re-renders come from and what actually reduces them.

  6. Custom Hooks

    Extracting reusable logic, and the rules that constrain how.

  7. Rebuilding useHooks

    Reconstructing a library of around fifty hooks as the main practical exercise.

  8. Concurrent Rendering

    The concurrent model and what it changes about when work happens.

  9. React on the Server

    Server rendering and the boundary between server and client.

  10. React Interview Questions

    A closing section applying the material to interview-style problems.

    Harvard University (CS50)

    Artificial Intelligence

    CS50's Introduction to Artificial Intelligence with Python

    Harvard's AI course, published free as OpenCourseWare. Seven lecture topics work through search, knowledge representation, uncertainty, optimisation, machine learning, neural networks and language, with Python projects attached to each. It is explicitly a follow-on rather than a first course: the stated prerequisite is CS50x or roughly a year of Python experience, and the material assumes the learner can already write and debug their own programs.

    Programming

    CS50's Introduction to Computer Science

    Harvard's introductory computer science course, taught through eleven weeks that begin in Scratch and move into C, then Python, SQL and web development with Flask. It spends unusually long on what happens underneath a program, covering arrays, memory, pointers and data structures, before reaching higher-level languages, and ends with a self-directed final project. The course materials are free; a certificate is a separate paid option through edX.
