This course will equip you with the key concepts & skills you’ll need to become proficient with the TypeScript language, and acquaint you with the production-grade tooling, workflows, and resources you’ll want to accelerate your productivity and career growth.
By taking this course, you'll:
- Understand how TypeScript differs from JavaScript, and the advantages TS offers
- Install & configure TS in a new or existing codebase
- Add type annotations to variables, function arguments & return values
- Work with custom types & interfaces, including complex types, unions & generics
- Get acquainted with popular libraries from the open-source TS ecosystem
- Set up your professional workflow for full-stack TS development
TypeScript is the industry’s preferred way to bring some order to the notorious unpredictability of JavaScript’s weak typing, allowing us to write more stable, production-ready web apps. In this course, we’ll get to know TypeScript through hands-on refactoring exercises, as we use increasingly complex TS features to stabilize a buggy JS app. Beyond exploring the language itself, we’ll also get familiar with popular TS tooling and workflows for full-stack development. By the end of the course, you’ll be a productive TypeScript developer ready to deepen your knowledge with further courses on FrontendMasters.
