+Converts the values of RGB components to a hexadecimal color code.
+
+- Convert given RGB parameters to hexadecimal string using bitwise left-shift operator (`<<`) and `Number.prototype.toString()`.
+- Use `String.prototype.padStart()` to get a 6-digit hexadecimal value.
+
+```js
+const RGBToHex = (r, g, b) =>
+  ((r << 16) + (g << 8) + b).toString(16).padStart(6, '0');
+```
+
+```js
+RGBToHex(255, 165, 1); // 'ffa501'
+```
