Curries a function.
|
|
|
|
- Use recursion.
|
|
- If the number of provided arguments (`args`) is sufficient, call the passed function `fn`.
|
|
- Otherwise, return a curried function `fn` that expects the rest of the arguments.
|
|
- 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 = (fn, arity = fn.length, ...args) =>
|
|
arity <= args.length ? fn(...args) : curry.bind(null, fn, arity, ...args);
|
|
```
|
|
|
|
```js
|
|
curry(Math.pow)(2)(10); // 1024
|
|
curry(Math.min, 3)(10)(50)(2); // 2
|
|
``` |
