Frequently Asked Questions
Is TypeScript mandatory for frontend developers in 2026?
Yes. Nearly 90% of mid-to-senior frontend engineering job openings require proficiency in TypeScript due to its type-safety and maintenance benefits.
Should I learn React or Next.js first?
Start with pure React fundamentals (hooks, state, props, component lifecycle). Once comfortable, transition to Next.js to learn Server Components, SSR, and dynamic routing.
What is the fastest way to get hired as a junior frontend developer?
Build 2-3 polished, deployed full-stack or API-driven projects using Next.js and Tailwind. Share clean GitHub repositories with thorough READMEs and host them live on Vercel.
