wrap.js (written in ES6)
Returns a function that wraps input values such that [0 <= x < size].
Useful for carousels etc, where one should be able to click right and end up in the beginning. Uses the correct modulo operation, not the javascript style.
Install:
npm install wrap.js
Run tests
npm test
with simple arrays:
import wrap from 'wrap.js';
const wrapValue = wrap(4);
[1,2,3,4,5].map(limiter);
Can be used with frp libraries (e.g. Bacon.js, RxJS, Kefir.js). Examples are written with Bacon.js
in frp:
import wrap from 'wrap.js';
import Bacon from 'baconjs';
let stream = Bacon.sequentially(1000, [1, 2, 3, 4, 5])
.map(wrap(4));
stream.log();
