Essential skills that a React developer should have

  • JavaScript proficiency

React is based on JavaScript, so a solid knowledge of this programming language is essential. A React developer must have a deep understanding of fundamental JavaScript concepts, such as functions, objects, arrays, scope, closures, and event handling. Additionally, it is important to familiarize yourself with more advanced features of JavaScript, such as promises, async/await, and the use of modules.


“JavaScript is the most important skill for developers to have. As a result, it's critical to test your understanding of JavaScript fundamentals such as code structure, variables, data types, arrays, and more. As a result, they do have an excellent fundamental understanding. Their coding talents will be valuable in the design of a high-performance program”, they highlight in an article on the Knowledgehut portal.


  • Understanding React Fundamentals

A React developer should have a solid understanding of React basics such as components, props, state, component lifecycle, and JSX. These concepts form the foundation on which robust and scalable web applications are built with React.

  • Experience with development tools

Familiarity with development tools like npm (Node Package Manager), webpack, Babel, and ESLint is crucial to optimizing the development workflow and efficiency in React. These tools help manage dependencies, compile code, detect errors, and maintain clean and consistent code.


  • Git

“Since React is a robust JavaScript library with reusable components, it is very important to know how to use Git repositories to share code and other components with other developers. Git allows React developers to share and update web application projects on various coding forums such as GitHub, Gitlab and BitBucket”, they explained in an article on the Computer Society portal.


  • Ability to work with REST APIs and GraphQL

In the real world, React applications often need to communicate with backend servers through APIs. Therefore, it is important for a React developer to have experience working with REST APIs and GraphQL to make data requests and update application state effectively.

  • Basic knowledge of HTML and CSS

Although React primarily focuses on the user interface layer, it is crucial to have a good understanding of HTML and CSS to develop attractive and accessible user interfaces. This includes knowledge of responsive design, CSS styles, and web accessibility.


“React JS is a front-end development framework. The interface of the app is fascinating to attract the users and entice them to interact with it. Regardless of the type of business or application you are about to create, every ReactJS developer should have extensive knowledge in the fields of HTML and CSS”, they added in a LinkedIn article.


  • Unit and integration tests

It is important for a React developer to have experience writing unit and integration tests to ensure that the application works as expected and remains bug-free. Popular tools like Jest and React Testing Library are widely used for this purpose.

  • Troubleshooting and debugging skills

In software development, problems and errors are inevitable. Therefore, a React developer must have strong troubleshooting and debugging skills to efficiently identify, diagnose, and fix problems in the code.


Becoming a successful React developer requires more than just learning the basics of React. You need to master a wide range of skills, ranging from mastering JavaScript to understanding design patterns, development tools, and best practices.


By investing time and effort in developing these essential skills, React developers can stand out in the field and build high-quality web applications that meet the demands of users and businesses in the digital age.
