Ionic 3 group array objects by date how?


#1

Hi, I have a question. How can I group array objects by date?

my .ts file

    this.http.get("sample url")
      .map(res => res.json())
      .subscribe(data => {
        this.dataMatches = data.response.data;
        this.month = this.dataMatches[0].matchTime;
      }, err => {
        console.log(err);
      });

my screenshot
49%20PM

I want to group my array by date (matchTime);
