Modern frontend frameworks are useful, but strong fundamentals make every framework easier to understand.
By practicing HTML, CSS, and vanilla JavaScript first, you improve your understanding of:
- How web pages are structured
- How CSS controls layout and visual design
- How the DOM works
- How browser events work
- How user interactions update the UI
- How JavaScript handles state and logic
- How APIs connect frontend apps to external data
- How real frontend components are built without abstraction
These fundamentals make it easier to later work with React, Vue, Angular, Svelte, Next.js, and other frontend tools.
