Tuples
Create fixed-length, ordered collections in TypeScript using tuples to model structured data with precise type definitions.
Record
Learn how to use `Record<K, V>` in TypeScript to create strongly-typed object maps, and when it's better than regular objects.
TS Dictionary
Learn how to use a TypeScript dictionary to create and define key-value pairs, iterate efficiently, handle optional keys, ensure type safety, merge dictionaries, and update values.
Set
Learn how to use TypeScript Set for adding, removing, and checking elements, iterating, converting to arrays, and comparing Sets for equality.
Hashmaps
Create efficient, type-safe hashmaps in TypeScript using Map objects and interfaces to ensure predictable key-value access patterns.
Map Type
Build flexible generic map types in TypeScript that transform object properties while preserving type safety.
