Advanced Typing in TypeScript
#1about 4 minutes
Understanding the core design principles of TypeScript
TypeScript's design is based on core tenets like structural typing, powerful type inference, and support for common JavaScript patterns.
#2about 6 minutes
A practical example of typing the DOM API
The `addEventListener` method is typed using string literal types, the `keyof` operator, and an event map interface to provide type safety for different event types.
#3about 5 minutes
Designing a type-safe data pipeline inspired by Pandas
A type-safe data processing API can be designed to overcome the runtime errors common in libraries like Pandas by tracking the shape of data frames.
#4about 4 minutes
Using generic record types for table columns
The `Table` interface uses a generic type parameter constrained to `Record<string, any>` to represent named columns with specific types.
#5about 7 minutes
Implementing and demonstrating the data pipeline API
A live demo showcases the API's type inference capabilities for selecting, computing, and dropping columns from a table without explicit type annotations.
#6about 3 minutes
Answering questions on partial types and inference
The Q&A covers handling partial objects in constructors and demonstrates how TypeScript correctly infers the types of newly computed columns.
