Yes, TypeScript supports all existing JavaScript libraries, and type definitions (.d.ts files) provide typing support for most popular packages.

You’ll need Node.js, npm or yarn, and the TypeScript compiler (tsc). A code editor like Visual Studio Code provides the best support.

You’ll learn about TypeScript’s type system, objects, enums, functions, generics, compiler options, and how to design reusable, type-safe utilities.

Generics allow you to write flexible, reusable functions and classes while preserving type safety, making them ideal for APIs, libraries, and large-scale applications.

Yes, TypeScript is widely used by companies like Microsoft, Google, Airbnb, and Slack for building scalable, production-grade applications.

By completing the course, you will be able to confidently design, implement, and manage applications using TypeScript, with skills to build safer, cleaner, and more scalable code.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.
