How to Use Tuples in TypeScript | HackerNoon
Briefly

Tuples in TypeScript enable type-safe, fixed-length sequences that hold a set number of elements with varying types, ensuring values match the predefined structure.
Unlike arrays, tuples enforce an exact matching of types and order upon value assignment, which helps maintain consistency and clarity in data structures.
With tuples, developers can create named types like MyNamedTuple to instantiate variables, allowing clear representation of structured data like a person's name, age, and admin status.
The fixed-length nature of tuples lends itself well to representing ordered collections, such as coordinates or RGB color values, where the number of elements is predetermined.
