What will I learn?
The Javascript Development Course teaches you to build a small, complete app with a clean file structure, a Node.js and Express backend, and a responsive, accessible interface. You will design data models, implement REST APIs, handle fetch requests with async/await, and manage client-side state, while writing clear documentation, readable code, and simple tests for reliable, maintainable projects.
