Advanced TypeScript
Type complex applications with generics, conditional types and strict compiler settings in a small-group bootcamp.
Program overview
Over ten to twelve weeks you work in a small group with a lead instructor. Live sessions cover the type system in depth, and each week you apply it to a shared codebase. You finish by migrating a mid-sized JavaScript project to strict TypeScript.
What you'll learn
- Write generic functions and components with constraints
- Build conditional and mapped types for API shapes
- Use discriminated unions to model state
- Configure strict mode and fix the errors it surfaces
- Type third-party libraries with declaration files
Who it is for
Developers who already use TypeScript day to day and want to model harder problems in types.
Before you enroll
You have written TypeScript in at least one project and know interfaces, unions and basic generics.
