Adding Error Properties

Include extra context in errors

Custom errors can carry additional information. Add properties for error codes, affected fields, or recovery hints.

class ApiError extends Error {
  constructor(message, statusCode) {
    super(message);
    this.name = "ApiError";
    this.statusCode = statusCode;
  }
}

throw new ApiError("Not found", 404);

Extra properties help callers make better decisions.
