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
```
