ezzy‑config‑setup is a lightweight JavaScript utility that turns a flexible list of function arguments into a single, well‑structured configuration object, optionally merging it with defaults. It lets developers define expected argument types and positions (e.g., `method:string`, `config:object`) so the library can automatically map whatever order or combination of arguments are passed into the proper config properties—useful for building constructors or APIs that need Java‑style overload handling.
