+
+Calculates the date of `n` days from today as a string representation.
+
+- Use the `Date` constructor to get the current date.
+- Use `Math.abs()` and `Date.prototype.getDate()` to update the date accordingly and set to the result using `Date.prototype.setDate()`.
+- Use `Date.prototype.toISOString()` to return a string in `yyyy-mm-dd` format.
+
+```js
+const daysFromNow = n => {
+  let d = new Date();
+  d.setDate(d.getDate() + Math.abs(n));
+  return d.toISOString().split('T')[0];
+};
+```
+
+```js
+daysFromNow(5); // 2020-10-13 (if current date is 2020-10-08)
+```
