+Creates a function that invokes the provided function with its arguments transformed.
+
+- Use `Array.prototype.map()` to apply `transforms` to `args` in combination with the spread operator (`...`) to pass the transformed arguments to `fn`.
+
+```js
+const overArgs = (fn, transforms) =>
+  (...args) => fn(...args.map((val, i) => transforms[i](val)));
+```
+
+```js
+const square = n => n * n;
+const double = n => n * 2;
+const fn = overArgs((x, y) => [x, y], [square, double]);
+fn(9, 3); // [81, 6]
+```
