About this course

Modern web applications require scalable, maintainable, and type-safe code. TypeScript enhances JavaScript by adding static typing, modern object-oriented features, and strong tooling support, and it is widely used in frameworks such as Angular, React, and Node.js. This course helps students transition from basic JavaScript to professional front-end development practices, enabling them to build structured and maintainable web applications used in industry.
