📄️ TypeOf
Discover how to use TypeScript `typeof` for type checking, creating type guards, and distinguishing between primitive and complex types efficiently.
📄️ KeyOf Operator
Master the keyof operator in TypeScript to create flexible, type-safe property access and build more robust object manipulation functions.
📄️ as const Assertion
Use TypeScript's 'as const' assertion to create deeply immutable literal types and unlock powerful type inference.
📄️ Satisfies
Discover how to use TypeScript satisfies to ensure type conformity, apply type constraints, and enhance code reliability for improved type safety.
📄️ Index Signature
Define flexible object types in TypeScript using index signatures to handle dynamic property access safely.
📄️ Union Types
Discover how to define, check, narrow down, and handle TypeScript union types, along with implementing function overloads, combining with interfaces, and debugging errors.
📄️ Discriminated Union
Build discriminated unions in TypeScript to model complex states with exhaustive type checking that catches bugs at compile time.
📄️ Declare
Use TypeScript's declare keyword to provide type definitions for existing JavaScript libraries and global variables.
