Source code

We have several examples on the website. Here is the first one to get you started: This example will render "Hello Taylor" into a container on the page. You'll notice that we used an HTML-like syntax; we call it JSX. JSX is not required to use React, but it makes code more readable, and writing it feels like writing HTML. The main purpose of this repository is to continue evolving React core, making it faster and easier to use. Development of React happens in the open on GitHub, and we are grateful to the community for contributing bugfixes and improvements. Read below to learn how you can take part in improving React. Facebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read the full text so that you can understand what actions will and will not be tolerated. Read our contributing guide to learn about our development process, how to propose bugfixes and improvements, and how to build and test your changes to React. To help you get your feet wet and get you familiar with our contribution process, we have a list of good first issues that contain bugs that have a relatively limited scope. This is a great place to get started.

It is maintained by Meta (formerly Facebook) and a community of individual developers and companies. According to the 2025 Stack Overflow Developer Survey, React is one of the most commonly used web technologies.
