 * Checks if a value is an `arguments` object.
 * @param {*} value - The value to check.

 * @example
 * ```js
 * function myFunction() {
 *   return isArguments(arguments);
 * }
 * console.log(myFunction()); // true, since the `arguments` object is an instance of `Arguments`
 * isArguments([1, 2, 3]); // => false
