This concise 2-hour introductory course will give you a hands-on introduction to TypeScript. By the end, you'll have a solid understanding of the fundamentals of TypeScript and how to leverage it to create safer and more reliable JavaScript applications.
TypeScript is a "superset" of JavaScript, meaning all valid JavaScript code is also valid in TypeScript. However, TypeScript enhances your coding experience by enabling you to write code with greater confidence in the stability and longevity of your projects. This is done via compile-time checking, which identifies potential bugs before running the code, allowing you to fix issues proactively and prevent crashes in your programs. This ensures a smoother and more reliable development process (and less rage-quitting!) By providing a strong typing system and modern tooling support, TypeScript also provides a robust development environment. This makes it easier to refactor code, manage large codebases, and collaborate with other developers. This introductory course will equip you with the knowledge and skills to effectively integrate TypeScript into your JavaScript projects. Ready to make your code safer? Let's go! Please note that from February 27, 2025, this course will be closed for new enrollments. If you're already enrolled, you'll still have access to study the course here until December 29, 2025. After that, the course will be available at https://www.coursera.org/learn/learn-typescript/

The course may not offer an audit option. 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.
