In the array and parameter array functions, arguments is an object but not an array object. Arguments instanceof array: falsearguments instanceof object: true: Pass the array to the function as a parameter, argements only has one element to pass the parameter array to the function as a parameter. argements contains multiple elements to pass to the Function two parameters. Solution: use the parameter array var ARGs = ['1', '2']; fun. apply (null, argS); argements [0] = '1'; argements [1] = '2'; B scheme: directly pass two parameters fun ('1 ', '2'); argements [0] = '1'; argements [1] = '2'; incorrect solution: Fun (ARGs ); argements [0] = ['1', '2'];
