React Js Coding Interview Questions

React.js coding interview questions are valuable because they assess a candidate's proficiency in a widely used JavaScript framework for building user interfaces. By evaluating a candidate's skills in creating reusable components, handling state and props, and implementing data fetching and manipulation, interviewers can gauge whether they have the necessary knowledge and experience to contribute to a React.js development team. Additionally, these questions help identify candidates who are comfortable with the core concepts of React.js and can apply them to solve real-world problems in a dynamic and interactive environment.
