Intro to React
React is a free and open-source front-end JavaScript library for building user interfaces based on UI components. It is maintained by Meta and a community of individual developers and companies.
This course is for developers who want to learn the React library while learning the latest techniques currently emerging in the JavaScript language. This is an exciting time to be a JavaScript developer. The ecosystem is exploding with new tools, syntax, and best practices that promise to solve many of our development problems. Our aim with this book is to organize these techniques so you can get to work with React right away.
We’ll get into state management, React Router, testing, and server rendering, so we promise not to introduce only the basics and then throw you to the wolves.
You’ll be better prepared for the contents of the book if you’re comfortable with HTML, CSS, and JavaScript. It’s almost always best to be comfortable with these big three before diving into a JavaScript library.
