React
A JavaScript library for building user interfaces with a component-based architecture and declarative rendering model.
How to verify React skills
Get matched with a peer
Lemma's matching engine pairs you with a practitioner who complements your React level. Both of you benefit from the session.
Demonstrate your skills live
In a video session, you work through real React problems. Your peer observes your approach, reasoning, and output quality.
Build your evidence trail
Session evidence feeds into your React SCI score automatically. Each session adds to your verifiable track record.

Frequently asked questions
How do I verify my React skills on Lemma?
Complete a peer session where you build or review React components live. Your session partner evaluates your understanding of hooks, state management, and component design. Evidence is recorded and contributes to your SCI score.
What does a React SCI score measure?
Your React SCI (Skill Credibility Index) reflects demonstrated ability across component architecture, state management, performance optimization, and testing. It is computed from peer session evidence, not self-assessment.
What React concepts should I know before a peer session?
Solid understanding of hooks (useState, useEffect, useContext), component lifecycle, JSX, props vs state, and basic patterns like lifting state up. Advanced sessions may cover concurrent features, suspense, or server components.
How does React verification compare to a coding bootcamp certificate?
Bootcamp certificates prove attendance. Lemma verification proves demonstrated ability through live peer sessions with recorded evidence. Employers can verify exactly what you built and how you reasoned through problems.
