How a React quiz helps you learn the library

Learning React means keeping hooks, props and state straight, and rereading docs alone rarely locks them in. A React quiz maker turns your own course notes, slides or handouts into practice questions, so you test recall instead of recognition.

Read an explanation for every answer, right or wrong
Mix true/false with multiple-choice to catch common React misconceptions

Example React quiz questions with answers

Which hook runs side effects after a function component renders?useEffect. It runs after render, and its dependency array controls when it runs again.

True or false: a child component can change the props it receives.False. Props are read-only in the child, so changes must come from state in the parent.

Why does a list rendered with map() need a key on each item?Keys let React match elements between renders, so it updates only the items that changed.

What does calling a state setter like setCount do that assigning a new value to a plain variable does not?It schedules a re-render with the new value, while changing a plain variable does not update the screen.

What does useState return?An array holding the current state value and a setter function, which is why it is destructured.

Generate the full set

Three question types

Multiple-choice, true/false and short answer questions, so you can check recognition and recall of the same React concept.

Explanations on every question

Each answer comes with a short explanation, so a wrong guess about useEffect or keys becomes a lesson rather than a dead end.

Built from your own material

Questions come from the notes, slides or PDFs you upload, so the quiz matches the exact React course or workshop you are studying.

How it works

Upload or paste your material

Add a PDF, DOCX, PPTX, plain text notes or a photo of a page. Images are read with text recognition.

Pick a question type

Choose multiple-choice, true/false or short answer, then generate the set.

Answer, read, repeat

Work through the questions, read the explanation for anything you missed, and come back to the weak spots.

Start with a single topic, such as useState or component rendering, and paste the notes or upload the slides from that session. Work through the questions, read the explanation for each one you missed, then generate a fresh set from the same material before your next review.
