When working with React, there are a few best practices that should be followed in order to make sure your code is clean, maintainable, and easy to work with. 

One best practice is to make sure your component's props and state are as simple as possible. Props and state should only be used for the data that is absolutely necessary for your component to render correctly. Any extra data should be kept outside of your component, in a separate data store. 

Another best practice is to keep your component's render() function as simple as possible. The render() function should only be responsible for returning the JSX that renders your component's UI. Any extra logic should be moved out of the render() function, into separate functions. 

Finally, it's always a good idea to make sure your component's are modular and reusable. This means that each component should only be responsible for a small part of your overall UI, and that each component should be able to be used in multiple places throughout your application. 

Some additional pointers regarding best practices followed in React JS are as follows: 
1. Keep your components small and focused: 
2. Use functional components over class-based components 
3. Use the latest version of React 
4. Use prop types 
5. Use controlled components for forms 
6. Use keys for lists 
7. Use a linter(linter helps to catch errors and enforce coding conventions) 8. Use a debugging tool 
9. Follow Test Driven Development (TDD) 

Conclusion 
In conclusion, React JS is an incredibly powerful JavaScript library that enables developers to create rich user interfaces with ease. With its component-based architecture, virtual DOM support and a vast selection of libraries available, it provides a great basis for modern web development projects. Through this blog post, we have seen the numerous advantages offered by React JS and how developers can make use of these features when building dynamic applications. 

Additionally, we have provided coders with step-by-step guidance on core concepts in the library as well as prerequisites needed for improved onboarding experience so they can become proficient in utilizing all that React JS has to offer quickly and effectively. All in all, React JS is a highly capable library that should be considered when looking into modern frontend development solutions; empowering users with efficient solutions while reducing overall costs associated with application development.
