+Creates a function that invokes `fn` with `partials` appended to the arguments it receives.
+
+- Use the spread operator (`...`) to append `partials` to the list of arguments of `fn`.
+
+```js
+const partialRight = (fn, ...partials) => (...args) => fn(...args, ...partials);
+```
+
+```js
+const greet = (greeting, name) => greeting + ' ' + name + '!';
+const greetJohn = partialRight(greet, 'John');
+greetJohn('Hello'); // 'Hello John!'
+```
