Type Error in TypeScript Function Parameter This example demonstrates a common type error in TypeScript when passing an array to a function that expects a string.

The function greeter expects a single string, but an array of strings is provided. TypeScript's type system correctly identifies this mismatch and throws a compilation error.

Microsoft shipped TypeScript 5.8 with improved type checking in some scenarios, but thorny problems caused the dev team to delay related work to the next release.
