Current blog posts and consolidated historical articles from various other blog platforms used previously

blog.thi.ng

Due to a current lack of a proper blog setup, this is a temporary place to host & publish new blog posts (restarted in Dec 2022). My existing blogs with various long form articles originally published at Medium (2015-2020), the defunct toxiclibs.org site (2006-2011) and the ancient toxi.co.uk (2003-2008) are all in the process of being migrated to here as well...

blog's Issues

2019 transducers Part 2

Hi,
I've been meaning to read this article, finally did, and it was full of insights.
I discovered a few minor issues.

the resulting array as a comment:

// Replicate Array.map()
transduce(mul10, push(), null, [1, 2, 3, 4]);
// [10, 20, 30, 40]

same here:

// overlaps can be achieved via optional step size
tx.transduce(tx.partition(3, 1), tx.push(), tx.range(10));
// [
//   [0, 1, 2],
//   [1, 2, 3],
//   [2, 3, 4],
//   [3, 4, 5],
//   [4, 5, 6],
//   [5, 6, 7],
//   [6, 7, 8],
//   [7, 8, 9],
// ]

update converge condition from 1e-3 to 1:

// leaky integrator which stops when difference between
// prev/curr goes below 1
[
    ...tx.converge(
        (a, b) => Math.abs(a - b) < 1,
        tx.iterate((x) => x + (100 - x) * 0.5, 0)
    ),
];
