The modularity of the React ecosystem is extremely powerful for building applications. However, it makes learning React a nightmare when first starting out. To even get a React app up and running, you need the right combination of React, Webpack, and Babel. In this course we'll start from a blank folder and we'll build an application that encompasses everything you need to get started building production ready applications with React (including Routing and Ajax requests). With an average rating of 9.3/10 from 2,945 reviews, this could be the most popular and highest rated way to learn React. Recently updated and compatible with React 16.3.


Experience with the web platform (HTML, CSS, JavaScript) will help, but if you're coming from a different programming language, it isn't required. If you're a complete beginner, this course may be a struggle but you're welcome to try it out.

What devs are saying

This is hands down the best introduction to React on the web. It was 100% worth the money!!

Tyler knows his stuff, more importantly, he cares. He conceived this React Fundamentals course in the most thoughtful manner. His style of instruction is a breath of fresh air for me giving all the courses I have taken on Udemy, Udacity, Lynda, and Codecademy.

TylerMcGinnis's React Fundamentals course was extremely high quality and you get waaaaay more than what you pay for. The videos go deep into the usage and implementation of React, the React eco-system, and the work-along project sufficiently covers most aspects of the front end web development. I would recommend this course to those just past the JavaScript beginner stage as well as for experienced JavaScript Engineers who want to learn more about React. offers the most comprehensive React courses on the planet. The React Fundamentals course has helped my React, JavaScript and overall development skills grow quickly and profoundly in just a few days. Still, after completing this course, I continually reiterate over the material and always feel like a better developer because of it. Definitely the best resource out there!

I have spent the past 6 months or so banging my head against my desk trying to level up on my JS/Web App skills and this course was nothing but 'Aha!!' moments. I strongly recommend putting in the time and keep revisiting items you might not understand that Tyler brings up because they will eventually make sense. I can't wait to start kicking work in it's butt!

I went through the Fundamentals course in about a week, and I can honestly say it's been the most clear, concise, to-the-point course I've ever done. I feel that everyday I've been excited to resuming where I left because, after every lesson, I had gained significant knowledge and usefulness of React.

This is one of the best courses that I have found on the internet, not only for React but as a programming course in general. It is very well structured and I noticed that whenever a question would pop up in my mind, Tyler would address it within a minute in the video. So it is clear that he has quite some experience teaching this subject and is aware of the unclarities that a new-comer to React might have.

Out of all the React tutorials and courses I have worked through, this one is easily the best. Tyler explains complex topics in an understandable and digestible way, using multiple learning vectors (text, video, quizzes) to reinforce learning. If the other courses he offers are similar in style and quality, they are worth every penny.

Tyler's course on React was extremely helpful to me as it was very to the point and at the same time in depth. I'll be back for more courses for sure. He has the best explanation of "this", "apply", "call", and "bind" out there.

This is without a doubt the best React tutorial that I have seen. In addition to the basics covered by almost all tutorials, it includes important ancillary features like routing, as well as covering real world practices such as the container/presentational component pattern, and using axios for async calls, gives the viewer insight to how React is actually used by developers. Finally, the intro to webpack shows you how to get it all actually up and running with a local dev server. The tutorial was very well organized, excellently explained, and intelligent in the features that it included.

This is the best way to learn. During the training videos, he answers questions as I think of them! It's like he's reading your mind as you watch and code along.

This is the best React course I have taken so far. Tyler does an incredible job teaching everything about React as a starter. There is ton of information he takes into stages and defuses it into details with clarity. Anyone who is thinking of learning React should first dive into Tyler's ReactJS Fundamentals before considering other resources online.

This is by far the best intro course to ReactJS out there. Tyler has clearly put in a lot of work to make this course meaningful. If you're curious about React, or if you've finished other intro courses and come away more confused than when you started, this is pure gold. Absolutely take the time to go through building the app with Tyler and you'll be 100% more comfortable with React.

Tyler takes a rare, but awesome, "I don't assume you know anything" approach to teaching this course. Sometimes, even with a lot of coding experience, taking courses while learning a new language/framework can be frustrating because the authors assume you know some things (like what NPM is or how Webpack and Babel work). Tyler explains those things (very well) without making the viewer seem like an idiot. Incredibly thorough course clearly made with intention and planning. Kudos, Tyler!

As someone with a background in instruction and instructional design, I immediately recognized Tyler's course as a cut above the glut of "learn React" content, currently available. His material is well organized, the concepts build in an intuitive way, and the instruction is clearly-articulated, easy to follow, and blessedly free of annoying misdirects and content-padding that bog down other online courses.
