compare dates in typescript

 compare two dates 

    var date=new Date().toLocaleDateString();

var date2=new Date(this.invoiceOject.invoiceDate ).toLocaleDateString();

if(date==date2){

  this.toastr.error(

    "Unable to delete,invoiceDate is not same as Today's date",    "CASH INVOICE",     { timeOut: 4000 }

  );

  return;

}

var let main difference is let dont work inside scope only not wokr outside

{let x= hello all}

you cannot call x outside only possible with var
