Tests:

  • Split

     
    for(let i=0; i<dates.length; i++) {
        let date = dates[i].split("-");
        let dateString = date[2]+"-"+date[1]+"-"+date[0];
    }

  • Substring

     
    for(let i=0; i<dates.length; i++) {
        let dateString = dates[i].substr(6,4)+"-"+dates[i].substr(4,2)+"-"+dates[i].substr(0,2);
    }
