This repository demonstrates a common TypeScript error: passing an array to a function that expects a string. The greeter function is designed to accept a string, but when an array is passed, a runtime error occurs. The solution showcases how to correctly handle this by either modifying the function signature or pre-processing the array before passing it to the function.
The bug.ts file contains the original buggy code. The function greeter expects a single string, but an array is passed to it causing an error.
