TypeScript for JavaScript Developers

This course is designed for JavaScript developers who want to upgrade their skills by learning TypeScript and writing more reliable, scalable code. TypeScript builds on JavaScript by adding static typing and powerful development tools that help catch errors early and improve code quality. You will begin with the fundamentals of TypeScript, including how it works, how to install it, and how it differs from JavaScript. From there, the course explores core TypeScript concepts such as basic types, arrays, tuples, enums, type aliases, and interfaces. Next, you will learn how to work with typed functions, optional parameters, and object-oriented programming using classes and access modifiers. The course also introduces advanced TypeScript features like generics, union types, and type inference that make your code more flexible and maintainable. In the practical integration section, you will see how TypeScript is used with Node.js and React, along with the process of compiling TypeScript into JavaScript. The course concludes with a mini project where you will build a typed API request module to apply everything you have learned. By the end of this course, you will have a strong understanding of TypeScript and how to use it effectively in modern JavaScript development.
