Returns a date after adding given number of business days.
- Use `Array.from()` to construct an array with `length` equal to the `businessDayCount`.
- Use `Array.prototype.reduce()` to iterate over the array, and increment `startDate` using `Date.getDate()` and `Date.setDate()`.
- If `startDate` falls on a weekend, update it again by adding either one day or two days to make it a weekday.
- Use `Array.from()` to construct an array with `length` equal to the `count` of business days to be added.
- Use `Array.prototype.reduce()` to iterate over the array, starting from `startDate` and incrementing, using `Date.getDate()` and `Date.setDate()`.
- If the current `date` is on a weekend, update it again by adding either one day or two days to make it a weekday.
