Frequently asked questions
Should I learn JavaScript before TypeScript?
Yes. TypeScript is JavaScript with types added. Learning JavaScript fundamentals first means TypeScript becomes adding clarity rather than learning a new language. Most TypeScript learning resources assume JavaScript knowledge.
How long does it take to learn JavaScript?
Basic literacy: 2-3 months of consistent practice. Comfortable building applications: 6-12 months. Senior-level skill including async patterns, performance optimization, and ecosystem fluency: years. The early progression is rewarding; the long middle is where most learners need persistence.
Should I learn a framework right away?
No. JavaScript fundamentals first. Frameworks (React, Vue, Svelte) build on JavaScript — learning a framework without fundamentals produces fragile knowledge. Spend the first 2-3 months on JavaScript itself, then add a framework.
Which framework should I learn?
React dominates job listings. Vue and Svelte have devoted communities and arguably better developer experience. For employability, React first. For personal projects, pick what you enjoy — frameworks are tools, not religions.
What about Node.js?
Node.js extends JavaScript to server-side. Learn JavaScript first, then add Node when you want to build back-end services. The Odin Project covers Node naturally in its full-stack curriculum.
