Learn TypeScript by Scrimba
This course introduces you to the essential building blocks of TypeScript through a hands-on approach—developing a simple pizza restaurant order fulfillment system. In this course, you’ll explore: basic types, defining custom types, typing objects and arrays, optional properties, manual and implicit typing, literal types, unions and intersections, type narrowing, function return types, void and any, utility types (Partial and Omit), and generics.
Course Highlights
- Understand the basics of TypeScript's type system to write safer and more maintainable code.
- Demonstrate how to add type annotations to variables, including orderId and other custom types.
- Define and use custom types such as Pizza and Order to represent data structures accurately.
- Apply type annotations to arrays and nested objects to ensure consistency in complex data.
- Use literal and union types to represent specific, constrained sets of values.
- Implement type narrowing to handle different value types explicitly and safely.
- Define function return types, including void, to clarify the intent and output of functions.
- Leverage TS-specific types like any and utility types like Partial and Omit to handle advanced use cases.
- Design and use generic functions to write reusable, type-safe code.
- Fix TypeScript warnings by explicitly typing function calls and refining utility types.
