► safeDateChange(from: Date, to: Date): Date

Defined in safeDateChange.ts:23

const date = new Date(2017, 0, 31);
newDate = new Date(date);
newDate.setMonth(1);

// Normally you would expect "newDate" month to be February, but since the date
// of the previous date was 31 and february max date is 28 (or 29), the actual
// "newDate" is "Match 3rd 2017" (or 2nd). Using this function keeps it at "February 28 2017"
