-Returns the weekdays count between two dates.
+Returns the weekday count between two dates.
 
-- Takes startDate and endDate as inputs.
-- Executes a while loop if startDate is less than endDate and increments count if startDate does not fall on a weekend.
-- Adds one day to startDate in an iteration and the loop exits when startDate becomes equal to endDate.
+- Use `Array.from()` to construct an array with `length` equal to the number of days between `startDate` and `endDate`.
+- Use `Array.prototype.reduce()` to iterate over the array, checking if each date is a weekday and incrementing `count`.
+- Update `startDate` with the next day each loop using `Date.getDate()` and `Date.setDate()` to advance it by one day.
