clamp.js

clamp.js (written in ES6)

Install:

npm install clamp.js

Run tests

npm test

Returns a function that clamps input values to range [min <= x <= max]. Useful for data structures like arrays. Swapping min and max is allowed and will be corrected.

with simple arrays:

   import clamp from 'clamp.js';

   const limiter = clamp(0, 3);

   [1,2,3,4,5].map(limiter); // [1,2,3,3,3]

in frp:

    import clamp from 'clamp.js';
    import Bacon from 'baconjs';

    const limiter = clamp(0, 3);

    let stream = Bacon.sequentially(1000, [1, 2, 3, 4, 5])
        .map(limiter);

    // every 1000ms stream emits a value which is mapped on clamp()
    stream.log();

    // result -> sequence of values over time: 1,2,3,3,3
