Why this course rocks

In this 143-part interactive tutorial, you'll learn how to build dynamic, interactive web applications with React.js.

With Scrimba’s head of education, Bob Ziroll, as a guide, you’ll get to know all the bang-up-to-date features of React, and fix them firmly in your memory by using them to create hands-on projects.

React is a free and open-source front-end JavaScript library. It was created by the developers at Facebook for use in their own products, including Facebook, Instagram, and WhatsApp . React is also used by Netflix, The New York Times, AirBnb, Discord, DropBox, and many other big companies. In short, it is one of the most popular JavaScript libraries in the world.

This course is filled with coding challenges that you'll complete by writing React code directly inside the Scrimba screencasts. Before you know it, you'll have written eight interactive React applications!

You’ll be in fantastic company: over 100,000 students enrolled in Bob’s original React course. Many of them have taken to Twitter to tell the world how helpful they found it.

This course is designed to help you learn to code in a way that sticks - no more tutorial Hell.

We achieve this by stuffing the course full to the brim of interactive challenges, allowing you to develop the muscle memory you need to become a truly effective React developer.

You’ll also benefit from spaced learning and repetition in this course. Make sure you give yourself time (days/weeks) to finish it, and include lots of breaks. Don't try cramming it all in at once.

Don’t forget: learning should never be lonely - that’s why we’ve set up the Scrimba Discord server. Make sure you drop in, say hello, and share your goals and achievements. If you get stuck, there is even a dedicated React help channel.

Once you are done, you will feel confident in your React skills and be ready to continue your coding journey.

Advanced React bootcamp

Bob has also created a follow-up course that tackles more advanced React topics. Click here to check it out!

This course is also a part of our hugely popular Front-End Developer Career Path.

F to the A oracle

to the Q

Why is React popular?

React initially skyrocketed 🚀 to fame because it made fetching and showing data in your JavaScript apps much easier than before. Because React is "just" a library instead of an elaborate framework, it was - and still is - relatively easy to learn.

Who uses React?

Facebook built React for their own products, which include Facebook, Instagram, and WhatsApp . React is also used by Netflix, The New York Times, AirBnb, Discord, DropBox, and many other big companies you've heard of.

What is React used for?

React is used for frontend web apps to detect user input, fetch data, and update the user interface with data. React does all this with maximum performance.

What can React do?

React mainly gives you a structured way to create reusable frontend UI components, handle user input, update UI components efficiently, and manage your data.

What isn't good about React?

You will find there is no predefined way to structure your app. To ensure you get the most from React, you'll need to spend a little more time researching and implementing popular and effective ways to structure your app.

Can I learn React without knowing JavaScript?

React doesn't rely on any advanced, mind-boggling JavaScript features but you absolutely should know the basics of JavaScript before attempting learning React; otherwise, you're in for a hard time.

Is React a framework or a library?

React is a library - a library of helpful functions and modules to pull into your app as and when you need them. This means you're in complete control of your app. A framework, by definition, is the essential support for your app, which you build on and operate within.

Can I use React with WordPress, Django, PHP, and other backend tools?

Yes, absolutely. In the early days, React probably worked best with Node.js but in 2021, it's free game. React is a fantastic candidate for any backend framework.

How much do React developers get paid?

Salaries can vary greatly from $40K to $100k and beyond. It depends on your aptitude, attitude, and location!

Do I need to have taken Bob's original React course before I do this one?

No. This course replaces Bob's original React course, and is designed to include all the need-to-know modern features of React.

What are Solo Projects?

Solo Projects are real-world projects that are tailored to your skill level as you progress through the course. Use them to stress-test your skills and get projects for your portfolio. Most of the Solo Projects on Scrimba are only accessible for Pro Members.

What if I'm half way through Bob's old course?

Do not worry! Anything you've already learned will still be useful, for example when dealing with legacy code. However we recommend you switch to this course so that you're learning the newest features of React.
