+Checks if the given date is a weekday.

+- Use `Date.prototype.getDay()` to check weekday by using a modulo operator (`%`).
+- Omit the argument, `d`, to use the current date as default.
+
+```js
+const isWeekday = (d = new Date()) => d.getDay() % 6 !== 0;
+```
+
+```js
+isWeekday(); // true (if current date is 2019-07-19)
+```
