Introduction
React is a JavaScript library for building user interfaces, particularly single-page applications, where you can create complex UIs from small and isolated pieces of code called "components." Regardless of your level of experience as a developer, using React is easy and enjoyable to begin. This is a guide to get you started with React.
React is maintained by Meta (formerly Facebook), and a network of independent developers and organizations manage React.
Reasons for Learning React
Before going into the details of how React works, it is necessary to know “why” you should learn React.
There are numerous compelling reasons to learn React, many of which are frequently cited by experts in the field
Accessibility of Learning React: While learning React might be more challenging for complete beginners, it becomes manageable once you have a solid grasp of JavaScript fundamentals. React's component-based architecture allows for the reuse of simple pieces of functionality across your application, streamlining the development process.
Large Ecosystem: Benefit from a vast community, rich libraries, and tools.
Career Benefits: Learning React not only opens up numerous job opportunities but also enhances your understanding of JavaScript, a critical skill throughout a developer's career. React has a large community of support, numerous open-source projects on GitHub, and a wealth of learning resources.
High Demand for React Developers: The job market for React developers is robust. In the United States, the average yearly salary for a React developer is $120,000. Numerous businesses rely on React, creating a continuous demand for skilled developers. With thousands of open positions, including remote opportunities, job security is strong for React developers.
Understanding essential JavaScript concepts and methods, such as map and filter, is crucial for mastering React.
React is a JavaScript framework, so it is necessary that you have a basic understanding of JavaScript fundamentals to grasp react .
Installation
To get started with React, you need to set up your development environment. Ensure Node.js and npm are already installed. To verify that Node is installed on your computer, simply open your terminal or command prompt and run node -v and npm -v. If it's installed, you'll see a version number; otherwise, there will be an error.
The best way to create a React project is by using create-react-app, a single command that comes with a built-in development server, build configuration, and more.
npx create-react-app react-app
When it is done the folder structure looks like this:
Then go into the new directory:
cd react-app
Run the code using:
npm start
Navigate to http://localhost:3000 to see the app. You should see something like the image below:
The folders can be edited to suit your project.
Conclusion
React simplifies the process of building dynamic and interactive user interfaces with its component-based architecture, declarative syntax, and efficient rendering mechanisms.
