- 1Open the repository. Go to the sudheerj/reactjs-interview-questions page on GitHub and read the README.
- 2Clone it if you want a local copy. Run the git clone command to download the files to your computer.
- 3Open the table of contents. Find the numbered Core React list and choose the first topic to study.
- 4Answer from memory. Read the question, then answer it in your own words before checking the README.
- 5Compare and note gaps. Check the README answer and write down anything you missed.
- 6Move through the topics. Work down the table of contents, returning to weaker topics before your interview.
What is reactjs-interview-questions?
The repository is a study reference, not a software tool. Its README describes it as a list of top 500 ReactJS interview questions and answers, and it is written in JavaScript.
The README notes that this repository is specific to ReactJS. For core JavaScript questions, it points to a separate JavaScript Interview Questions repository, and for data structures and algorithms it points to a Data Structures and Algorithms repository.
How do you get a copy of the questions?
The source lists no install steps beyond cloning the repository. You can also read the questions online on GitHub without downloading anything.
To clone it to your machine, run the command below.
git clone https://github.com/sudheerj/reactjs-interview-questionsHow is the question list organised?
The README opens with a table of contents, numbered and grouped under headings such as Core React. Each row links to the answer further down the page, so you can jump straight to a topic.
Early entries cover JSX, components, state versus props, the Virtual DOM and React Fiber. The table of contents is collapsible, so you can hide it when you are reading the answers.
- Click any question in the table of contents to jump to its answer.
- Use the Core React group as a starting point for the basics.
- Read the state versus props entry alongside the state and props entries, since they are closely related.
How should you study with it?
Work through a topic by reading the question, answering it aloud in your own words, and then checking the README answer. The repository is a reference, so repeating this for each topic is more useful than reading straight through.
The README says coding exercise questions are coming soon, so this is not a source of hands-on practice yet.
- Pick a topic, such as the Virtual DOM, and answer its question without looking.
- Compare your answer with the one in the README and note the gaps.
- Revisit weak topics before your interview.
Who should not rely on it alone?
The repository assumes you already know some React. If you are learning React from scratch, start with a learning resource first and use this list afterwards to check terminology.
Because the README says coding exercises are coming soon, pair it with hands-on coding practice if your interview includes live coding.
What people use it for
- Preparing for a React job interview by checking answers to common questions.
- Reviewing core terms such as JSX, state, props and the Virtual DOM before an exam.
- Giving yourself a quick refresher on React terminology.
- Building a reference list of common React questions as an interviewer.
Frequently asked questions
Is reactjs-interview-questions free to use?
Yes, the repository is licensed under MIT. The README does not list any paid tier for it.

The README lists no prerequisites. The repository assumes some existing knowledge of React, so it is best used as a review tool.
Can I learn React from this repository?
Not from scratch. It is a list of interview questions and answers, so it works better for checking and revising concepts you already know.

Our verdict
This repository suits developers preparing for React interviews, students revising core concepts, and interviewers who want a reference list. It is less suitable if you are learning React from zero or need hands-on coding practice, since it assumes existing knowledge and coding exercises are not yet available.
