What it is
This is a GitHub repository that collects ReactJS interview questions and their answers in one place. The README shows a table of contents covering core React topics such as JSX, components, state versus props, the Virtual DOM, and React Fiber. It is meant for people preparing for React job interviews, and it reads as a study reference rather than a software tool.
- Read through the core React questions to check your understanding before an interview
- Use the table of contents to jump to topics you are weakest on
- Practice explaining answers aloud to yourself or a study partner
- Follow the links to related JavaScript and data structures interview repositories mentioned in the README
Great for
- Developers preparing for a React job interview
- Students reviewing core React concepts before an exam or interview
- Developers who want a quick refresher on React terminology
- Interviewers looking for a reference list of common React questions
Not ideal for
- People wanting to learn React from scratch, since it assumes some existing knowledge
- People looking for hands-on coding exercises, because the description says coding exercise questions are coming soon
- People needing non-React JavaScript or data structures questions, which the README points to separate repositories for
