### Curry
|
|
|
|
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.
|
|
|
|
```js
|
|
const curry = (f, arity = f.length, next) =>
|
|
(next = prevArgs =>
|
|
nextArg => {
|
|
const args = [ ...prevArgs, nextArg ]
|
|
return args.length >= arity
|
|
? f(...args)
|
|
: next(args);
|
|
}
|
|
)([]);
|
|
// curry(Math.pow)(2)(10) -> 1024
|
|
// curry(Math.min, 3)(10)(50)(2) -> 2
|
|
```
