/**
* A generic exception class, which can be used to represent any kind of error.
* It's similar to the `DOMException`, but for any JavaScript environment.
*
* @example
* ```ts
* // throw an exception with a name
* import { Exception } from "@ayonli/jsext/error";
*
* throw new Exception("The resource cannot be found", "NotFoundError");
* ```
*
* @example
* ```ts
* // throw an exception with a code
* import { Exception } from "@ayonli/jsext/error";
*
* throw new Exception("The resource cannot be found", 404);
* ```
*
* @example
* ```ts
* // rethrow an exception with a cause
* import { Exception } from "@ayonli/jsext/error";
*
* try {
* throw new Error("Something went wrong");
* } catch (error) {
* throw new Exception("An error occurred", { cause: error });
* }
* ```
