 If you want to curry a function that accepts a variable number of arguments (a variadic function, e.g. `Math.min()`), you can optionally pass the number of arguments to the second parameter `arity`.
 
 ```js
-const curry = (f, arity = f.length, next) =>
-  (next = prevArgs =>
-    nextArg => {
-      const args = [ ...prevArgs, nextArg ];
-      return args.length >= arity ? f(...args) : next(args);
-    }
-  )([]);
+const curry = (fn, arity = fn.length, ...args) =>
+  arity <= args.length
+    ? fn(...args)
+    : curry.bind(null, fn, arity, ...args)
 // curry(Math.pow)(2)(10) -> 1024
 // curry(Math.min, 3)(10)(50)(2) -> 2
 ```
