@nameof/nameof/dist/index.js

A tiny utility for safely extracting property names from TypeScript objects — inspired by C#'s [`nameof`](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/nameof) operator.

// index.ts
function nameof(...args) {
  const lastArg = args.at(-1);
  if (typeof lastArg === "function") {
    return lastArg.name;
  }
  if (typeof lastArg === "object" && lastArg !== null) {
    const k = Object.keys(lastArg).at(0);
    if (k) {
      return k;
    } else {
      throw new Error("Object must have exactly one string-key property");
    }
  }
  return lastArg;
}
export {
  nameof,
  nameof as default
};
