I was not aware of the data-last convention. Thanks! Makes a lot of sense.

My mental model of assign was backwards, and it took me a while to comprehend why their implementation would be data-last.

So, the data is the object that is being modified? And the idea is it lets you write stuff like this more easily:

    const addStuffToObject = stuff -> object -> assign({ "some_stuff": stuff }, object);
    const addWeirdStuff = addStuffToObject("weird stuff");
    const weirdObj = addWeirdStuff({ "foo": "bar" });

Yes, and this sort of application (pun intended) is what the one-liner library is for.

If you have a function isEqualTo(a, b), you can curry(isEqualTo, 5) and filter with it.

`assign` could be used in the same way for assigning/overwriting the same field in an array of Objects, and so on.
