# furry

Fast¹ `curry` and `unstage` with *cyclical placeholder semantics*²

```js
const {_, curry, unstage} = require('furry');

const a = 1, b = 2, c = 3;

const f = curry((a, b, c) => a - b * c);
const g = unstage(3, a => b => c => a - b * c);

[
  f(a, b, c),
  g(a, b, c),
  f(_, _, c, _)(b, a),
  g(_, _, c, _)(b, a),
  f(_)(_)(c)(_)(b)(a),
  g(_)(_)(c)(_)(b)(a),
  f(_, _, c, _, b, a),
  g(_, _, c, _, b, a)
]
.every(x => x === -5)
```

## `2` Cyclical placeholder semantics

Rather than the placeholder flipping the argument with the next, the argument
is flipped with the last. To learn more, check out [my Gist explaining the idea][1].
