React quiz

Sharpen your React knowledge: JSX, hooks, state, and the component model. These questions mirror what teams ask when hiring for modern web UIs.

This run has 10 questions. Each item may have 1 to 4 correct answers - mark all that apply. You have 20 seconds per question.

Select every answer that applies (1-4 may be correct).

React roles expect solid hooks, state, and performance intuition. Use this quiz as a warm-up; follow up with JavaScript and TypeScript quizzes when job posts mention a full modern front-end stack.
