React Developer key facts & eligibility
| Conducting body | React is maintained by Meta and the open-source community (there is no single official React certifier) |
|---|---|
| Official website | react.dev ↗ |
| Mode | IMPORTANT: there is no standalone official React certification exam. Meta (React’s creator) offers React course certificates through Coursera — the Meta Front-End Developer Professional Certificate and the Meta React Specialization — and various third parties offer React certifications, but none is an official React “developer” credential. |
| Scoring & marking | This practice covers React developer fundamentals — components and JSX, props and state, hooks (useState, useEffect, useContext and others), rendering lists and keys, forms and events, the component lifecycle, and basic performance and testing. To gain a recognised credential, consider Meta’s React courses on Coursera or a reputable third-party certification. |
| Score validity | Not applicable — there is no standalone official React exam; course certificates are issued on completion. |
| Language | English. |
