        let [a0, b0, c] = [12, 5, 8];

        let {d,e,f} = {d: 12,e: 21,f: 23};

        console.log(a0, b0, c);

        // 结果12,5,8

        console.log(d, e, f);

        // 结果12,21,23

        let [{a,b},[n1, n2, n3], num1, str1] = [{a: 1,b: 2},[12, 5, 8], 8, 'cxzcv'];

        let [json,arr, num2, str2] = [{a: 1, b: 2},[12, 5, 8], 7, 'cx']

        console.log(a, b, n1, n2, n3, num1, str1);
