Write better code with TypeScript’s language features
Writing large applications in JavaScript is a challenge. TypeScript brings JavaScript down to earth by providing optional static typing and future JavaScript features today. TypeScript gives the developer instant feedback on the code they are writing in order to catch mistakes earlier in the development process. Since it is transpiled to JavaScript, developers can take advantage of future JavaScript language features today.
This course will take you on a journey through interacting with the type system to working efficiently with more advanced features of the language. It will strengthen your knowledge of TypeScript and help you see the benefits it brings. We use an example-based approach that walks you through a restaurant ordering sample application. In addition, we go one step further by showing you how to automate custom checks on a code base and how to close statically typed gaps.
An advanced guide for TypeScript filled with example-based walkthroughs and best practices.
What You Will Learn
- Compile the sample application and analyze its overall structure
- Understand TypeScript’s type system and how to use it more effectively
- Utilize the information from static types to enforce strictness and reduce mistakes
- Broaden your knowledge of ES6 classes and how they relate to class-like pre-ES6 patterns
- Interact efficiently with the type system for better structured code
- Familiarize yourself with using JavaScript libraries in TypeScript
- Improve your code with TypeScript language features
- Use advanced experimental ES6, ES7, and ES8 features
