“The React.js Fundamentals course is of the upmost quality. The depth of knowledge and attention to detail in each of the lessons is unsurpassed by any other course I have seen on the topic.
- Wyatt Preul, Software Architect, nearForm
“The React.js Fundamentals course produced by Jeff at CodeWinds is superb! It is a major boost to any developer coming up to speed with React. Jeff presents the concepts in an incremental approach offering detailed explanations when necessary. The courses are perfect for both absolute beginners as well as seasoned developers. All skill levels will walk away from this course with at least a few lessons learned, if not many.
Highly recommended!
- Kevin Old, Senior Software Engineer
“Jeff made me a React believer! Coming from an Angular-1 background, React was quite a revelation …
Jeff’s course is a very thorough and well-thought-out approach to learning React. You start with the basics, quickly seeing results (initially with CDN) that provides positive reinforcement.
Overall I would give this React.js course a 4-star thumbs up!

How is this course different from other online React.js courses?

  • This is a step by step project based course which builds a real working app using test driven principles (TDD/BDD). I teach and build apps with an incremental approach that reinforces the skills as you proceed.
  • React.js is taught using the latest recommended practices and the course is updated as new versions are released. Upated for React.js v15.
  • In this course I provide and explain the configuration for an auto building development environment which is essential for productivity.
  • This course is bundled with access to an exclusive online learning community where you will connect with instructors and students for help and encouragement during the course and beyond (mentoring and consulting for applying React.js to your own real world projects).
  • The online community is delivered with a real-time discussion forum that allows for searchable rich persistent conversations. If you have ever tried to follow conversations in a chat application, you’ll appreciate the ability to have separate threaded conversations which are easy to follow and can become the basis for additional discussion.
  • This course provides homework challenges in addition to the project which help solidify your skills. Professional and Enterprise packages also include personal review and feedback for your homework helping you to know you are using React.js properly.
  • Finally, with this course you have priority access to me, a veteran software engineer, who enjoys teaching and will do everything I can to help you succeed. I want you really understand React.js and know how to apply it appropriately. I’ll be here to coach, mentor, and consult with as you proceed through this course and apply these new skills to your own projects.

Is this course for a specific type or level of developer?

Intermediate JavaScript developers will flourish with this course. The course default pace and tempo should be right in their wheelhouse keeping them engaged and challenged. My base recommendation for this course is that you should have some JavaScript and HTML experience. You are not expected to be an advanced developer, but simply that you are comfortable in using JavaScript and HTML. It would also be beneficial to have some ES6 knowledge and a basic understanding of unit testing with JavaScript. I’ve written the course to be beneficial to all levels of JavaScript developers from beginner to advanced with a sweet spot for the intermediate developer. One advanced member who had been using React.js for over a year, mentioned that he still learned at least 10 important things from taking this course.

Do I have to understand ES6 (ES2015) features?

It would be helpful to have some familiarity with ES6 since the course is taught using the recommended practices of React.js with ES6. I have a brief review of the ES6 features that I use in the course, but if you want to go deeper, I will give you a list of additional resources that would be beneficial.

Do I have to use ES6 to use React.js?

You can use React.js without using ES6, but since most people will be using JSX with React.js, you will have a transpilation step in your dev environment using Babel. Given that you will have Babel in your toolchain, many people will want to start using some ES6 functionality since there are some really compelling features. Babel converts JSX and ES6 code into ES5 code that will run on older browsers, so there’s little reason not to use the newer ES features, especially given how it can improve the code.

Do I have to understand JavaScript testing?

It is useful to understand the basic ideas behind writing JavaScript tests, but the course will discuss a variety of testing frameworks available for testing JavaScript and will demonstrate test creation using Karma, Mocha, and Expect. Most people will be able to pick up the basics simply by following the course material.

Do I need to have any particular OS or tools to use this course?

This course and project code will work on Mac, Windows, and Linux or most anything that supports Node.js. You will need to use the editor of your choice to edit the code, nothing fancy is required. If you are familiar with git then it will be useful as you navigate the code, but there is also an alternative path which doesn’t require it.

Do I need to understand Node.js?

In the course, I walk you through the steps for installing Node.js and the tools we are using for the course to provide an auto build environment. It’s not necessary to have prior Node.js experience. We will use npm (the Node.js package manager) to download and install our JavaScript dependencies. Node.js tools will only be used for development purposes on your machine to generate JavaScript and CSS bundles. Node.js is not needed at runtime or on your servers.

I’m just starting out. Is this right for me?

I’d suggest that if you have some level of comfort using JavaScript and HTML then you can be successful using React.js. If you are just getting started programming or don’t really know JavaScript then you’ll want to get your footing with JavaScript first before taking this course.

How long do I have access to the videos?

Once you have purchased the course, you have perpetual or lifetime access to the videos. So while community access has a time period associated with it (which is renewable), the course videos, notes, code, and transcripts are available with lifetime access. Professional and Enterprise users can download the videos for personal offline use.

Am I allowed to share the videos with my team?

All of the course material including videos, notes, and transcripts are copyrighted and licensed for individual use only, so each team member would need to purchase a copy. Companies with large teams may contact me to discuss a team discount.

What is the structure of the course?

The course is divided into 7 sections:

  • Getting Started - Course orientation, Using React.js from CDN to build simple apps
  • Environment Setup - Setup a local build environment for effective development and instant feedback
  • React.js Components - ES6 review, JSX, render, props, fetching and rendering data, project introduction
  • Testing React.js Components - JS testing tools discussed, Karma, Mocha, TDD/BDD
  • State, Forms, Events - handling state, creating forms, listening to events, form validation
  • Component Reuse - evolution of our project, adjusting components for better reuse, working with currency, sending data, handling keypress events
  • Next Steps - finding React.js components, continuing to learn

Each section has a series of short videos (2-10 minutes in length each), notes, project code, transcripts, and some homework challenges. In each section we add features to our course project in a test driven fashion just like you would develop an agile project of your own. At each step of the way we have a working project that continues to grow in features. There are a total of 48 videos which is over 3.5 hours of focused training material explaining not only how to apply React.js but providing an understanding of why.

Is my payment secure?

Yes, we use industry standard SSL to secure the transport and Stripe is handling the payment processing of your credit card. The credit card info goes directly to Stripe and never touches our servers.

What happens after I buy this course?

You will be immediately given links to register for the course and an email receipt will be sent to your inbox. If you are purchasing this for your team members then you may distribute the links to each of the intended recipients so they may instantly register.
