Wrangling Tuple Types

This technical article addresses a common TypeScript challenge: ensuring functions that conceptually return tuples (like a custom React hook) are correctly typed. It demonstrates the problem where TypeScript infers a union array type instead of a fixed-length tuple, leading to errors, and provides the solution of explicitly annotating the function's return type as a tuple.
