+### uncurry
+
+Uncurries a function up to depth `n`.
+
+Return a variadic function.
+Use `Array.reduce()` on the provided arguments to call each subsequent curry level of the function.
+If the `length` of the provided arguments is less than `n` throw an error.
+Otherwise, call `fn` with the proper amount of arguments, using `Array.slice(0, n)`.
+Omit the second argument, `n`, to uncurry up to depth `1`.
+
+```js
+const uncurry = (fn, n = 1) => (...args) => {
+  const next = acc => args => args.reduce((x, y) => x(y), acc);
+  if (n > args.length) throw new RangeError('Arguments too few!');
+  return next(fn)(args.slice(0, n));
+};
+```
+
+```js
+const add = x => y => z => x + y + z;
+const uncurriedAdd = uncurry(add, 3);
+uncurriedAdd(1, 2, 3); // 6
+```
