How to Become a React Developer

What You Actually Need to Know

• Solid JavaScript fundamentals -- weak JS skills are the most common reason React candidates struggle in interviews
• React core -- components, hooks, state, and how data flows through an app
• Basic CSS layout (Flexbox/Grid) -- you don't need to be a designer, but broken layouts are a red flag
• Working with a real API -- fetching data, handling loading/error states
• Git, and comfort reading other people's code, not just writing your own

Example: A Portfolio Project That Actually Stands Out

A weather-app clone is the most common portfolio project in existence -- it won't differentiate you. A stronger example: a small but complete app with real functionality (a habit tracker with data persistence, a budget tracker with charts, a job-application tracker) that handles genuine edge cases -- empty states, loading states, error states -- and is deployed live with a working public URL you can link directly in your resume and LinkedIn.

A Realistic Timeline

1. Weeks 1-4: JavaScript fundamentals, genuinely solid before starting React
2. Weeks 5-9: React core, routing, and forms -- build the first version of your portfolio project
3. Weeks 10-12: state management, testing, and performance basics -- polish the project
4. Ongoing: applying and interviewing while continuing to build and refine

Common Mistakes

• Jumping into React before JavaScript fundamentals are solid
• Copying tutorial projects without changing or extending anything, so you can't explain your own decisions
• Ignoring accessibility and responsive design entirely -- both come up in real interviews and real jobs
• Never deploying anything -- a project only on localhost carries far less weight than one with a live URL
