Use recursion.
If the number of provided arguments (`args`) is sufficient, call the passed function `f`.
Otherwise return a curried function `f` that expects the rest of the arguments.
If you want to curry a function that accepts a variable number of arguments (variadic function) like Math.min for example, you can optionally pass the number of arguments to the second parameter arity.
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 =>
const curry = (f, arity = f.length, next) =>
(next = prevArgs =>
nextArg => {
const args = [ ...prevArgs, nextArg ]
return args.length >= arity
? f(...args)
: next(args);
const args = [ ...prevArgs, nextArg ];
return args.length >= arity ? f(...args) : next(args);
}
)([]);
