just-flip example code broken/doesn't work as expected?

[vidhill]

I was looking at just-flip,

I thought the example code looked interesting so I copied it into runkit, however the code does not git the expected result, an in the comments
It actually fails with an error,

I tried to fix the example, but I couldn't quite work it out
something about the combination of just-flip and just-map-object

const flip = require('just-flip');
const map = require('just-map-object');
const curry = require('just-curry');

const numbers = {x: 5, y: 10};
const flippedMap = flip(map);
const double = curry(flippedMap, (_, number) => number * 2);
double(numbers) // {x: 10, y: 20];

Edit: Sorry I now realize you were referring to the README example code. It was wrong and I've updated it. Thanks for the bug report!

Hi, so I think the issue is just-curry doesn't work that way. It only takes the function as an argument, then saves subsequent args until it has enough.

function add(a, b, c) {
  return a + b + c;
}
curry(add)(1)(2)(3);

You want just-partial instead (note it uses undefined and not _ for the placeholder)

const flip = require('just-flip');
const map = require('just-map-object');
const partial = require('just-partial-it');

const numbers = {x: 5, y: 10};
const flippedMap = flip(map);
const double = partial(flippedMap, (undefined, number) => number * 2);
double(numbers) // {x: 10, y: 20]

Here's the runkit...

Hope this helps.

Love the repo (utility set) by the way.
