How to enable only specific dates in Angular 5?

Question

I have set of dates and I want to enable only those dates in .

\"ListOfDates\": [
      {
         \"startDate\": \"2018-01-01         


        

Answer 1

myFilter = (d: Date): boolean => {
  let enableFlag = false;
  this.ListOfDates.some((date) => {
    if (date.startDate === d) { // You can use any other comparison operator used by date object
      enableFlag = true;
      return true;
    }
  })
  return enableFlag;
}

Note: You will have to format the d and dates in ListOfDates to a standard format of your choice
