Not able to sort array of objects after adding values [closed]

问题

On a follow up to my question. I am trying to sort my array in different ways.

I first wanted to add the missing values in my array of objects and then wanted to be able to sort it. Since my data is dynamic, I created a function and then called it based on how I wanted it sorted.

I am not getting any errors but I am still not able to do the sorting.

My code:

var json = [{
        "date": "2020-01-01T00:00:00.000Z",
        "metric": 32,
        "type": "Google"
    },
    {
        "date": "2020-01-01T00:00:00.000Z",
        "metric": 24,
        "type": "Bing"
    },
    {
        "date": "2020-02-01T00:00:00.000Z",
        "metric": 1,
        "type": "Google"
    },
    {
        "date": "2020-02-01T00:00:00.000Z",
        "metric": 32,
        "type": "Jeeves"
    },
    {
        "date": "2020-03-01T00:00:00.000Z",
        "metric": 24,
        "type": "Bing"
    },
    {
        "date": "2020-03-01T00:00:00.000Z",
        "metric": 30,
        "type": "Google"
    }
    ];

    const the_series = (cat, data, group, metrics) => {     
        let cat_arr = [];
        vals = data.map(val => {
            return val[cat];
        });
        vals.forEach(v=>{
            if (cat_arr.indexOf(v) === -1) cat_arr.push(v);
        });
        console.log(cat_arr);

        const gp = (array, key) => {
            return array.reduce((a, c) => {
                (a[c[key]] = a[c[key]] || []).push(c);
                return a;
            }, {});
        }

        const get_gp = gp(data, group);

        for (a in get_gp) {
            cat_arr.forEach(t => {
                if (!get_gp[a].some(v => v[cat] == t)) {
                    let f_gp = get_gp[a][0][group];
                    let f_cats =  t;
                    console.log(group + ' -- ' + cat);
                    let inc = {};
                    inc[group] = f_gp;
                    inc[cat] = f_cats;
                    inc[metrics] = 0;
                    get_gp[a].push(inc);
                }
            });
            get_gp[a].sort((a, b) => cat_arr.indexOf(a[cat])-cat.indexOf(b[cat]));
        }
        console.log(get_gp);
        let series = Object.entries(get_gp).map(([key, group]) => ({
            ['name']: key,
            ['data']: group.map(entry => entry[metrics]),
            ['marker']: {
                symbol: 'circle'
            }
        }));
        console.log(series);
    }
    console.log('-------------------------STRINGS--------------------------');
    the_series('type', json, 'date', 'metric');
    console.log('-------------------------DATES--------------------------');
    the_series('date', json, 'type', 'metric');

I have created a fiddle.
