• Knowledge of JavaScript Tooling: Making use of computers that come with languages such as Babel, Webpack, and npm or yarn for handling dependencies and compiling apps. 

3. State Management Libraries:

• Learning Orientation: While hiring a candidate, you should look for someone who needs to learn new technologies and keep up-to-date with React, including all best practices for working with JavaScript and trends on the web. 
• Problem-Solving Skills: Keep track of problem-solving skills through coding quizzes, or how the candidates’ approach and solve problems using real-life cases. 

8. Portfolio and Project Experience:

• Real-World Projects: Check their portfolio or the GitHub repositories to assess how involved they were in React. The projects developed in JS, the quality of the code written by the candidate, and participation in any open source projects, if any,. 
• Complexity of Projects: Prefer candidates who have experience with projects of different sizes and with different features of React development tasks. 

9. Communication and soft skills:

• Effective Communication: Above all, good communication skills are essential when it comes to explaining technical novelties, sharing and developing concepts, and coordinating with colleagues.
