Fast MSD in-place radix sort for Uint32 numbers in JavaScript
const radixSort = require('./index.js');
const N = 10000000;
const arr = new Uint32Array(N);
for (let i = 0; i < N; i++) arr[i] = Math.floor(Math.random() * 4294967295);
console.log(`sorting ${N.toLocaleString()} uint32 numbers`);
// warmup
radixSort(arr.slice());

One of the most time-consuming parts is responding to issues. A lot of OSS maintainers will bend over backwards to try and understand your specific problem and diagnose it, to the point of setting up new test projects, fussing around with different Node versions, reading the documentation for build tools that we don't use, debugging problems in third party dependencies that appear to be involved in the problem... and so on. I've personally spent hundreds of hours of my free time doing these sorts of things to try and help people out, because I want to be a responsible maintainer and I

Could you elaborate on how this isn't working? What are you expecting to happen and what happens instead? If you enable web developer extensions, are there any errors in the console, and what are those errors, and in what browser and browser version do they appear?
