+Truncates a string up to a specified length.
+
+- Determine if `String.prototype.length` is greater than `num`.
+- Return the string truncated to the desired length, with `'...'` appended to the end or the original string.
+
+```js
+const truncateString = (str, num) =>
+  str.length > num ? str.slice(0, num > 3 ? num - 3 : num) + '...' : str;
+```
+
+```js
+truncateString('boomerang', 7); // 'boom...'
+```
