Typescript 中两个或多个数字数组的聚合

Question

I'd like to aggregate two or more number values from several arrays in Typescript. I have a data model as follows:

export class DataModel {

    date : string;
    number : any;

}

The main class has an array of DataModels itself:

export class CountryData {

    country: string;
    province: string;
    Long: any;
    Lat: any;
    dataset: DataModel[] = [];

}

Finally, I have an array of CountryData.

Exemple of two CountryData arrays with three DataModel values each one:

    let data: CountryData[];
    let country1: new CountryData();
    let country2: new CountryData();
    let countrySum: new CountryData();

    country1.dataset = [{'01/02/20',5}, {'01/03/20',10}, {'01/04/20',15}];
    country2.dataset = [{'01/02/20',5}, {'01/03/20',10}, {'01/04/20',15}];

    data.push(country1);
    data.push(country2);

I'd like to iterate the data variable and obtain a result like this into the countrySum.dataset:

[{'01/02/20',10}, {'01/03/20',20}, {'01/04/20',30}];

And this, will apply to n arrays in data. Anyone knows how to do this with functions like map, reduce or any other?

Thansk!
