  public getAllDay (begin: any, end: any) {
    const dateAllArr = new Array();
    const ab = begin.split("-");
    const ae = end.split("-");
    const db = new Date();

    for (let k = unixDb; k <= unixDe;) {
       dateAllArr.push((new Date(parseInt(k))).format().toString());
       k = k + 24 * 60 * 60 * 1000;
    }
    return dateAllArr;
  }

because the format method does not exist
https://developer.mozilla.org.


the format attribute does not exist on the Date type.


this code is more than a little wrong in every way. Why don't you make the requirements clear first?
unixDb unixDe the unit difference between these two values can be calculated with ms
K to increase by one day?

format () after the push function, it is a problem to call the format method even if Date has it! Date does not have a format () method.
can consider splicing or using toLocaleString ()
