Benchmark have been done using:

const { Bench } = require('tinybench');
const data = [...Array(100)].map(() => Math.floor(Math.random() * 0xffffffffffff));
const bench = new Bench({ warmupIterations: 20, iterations: 1_000_000 });
bench.add('old', () => {
  for (const value of data) {
    uintToBase32StringMapperOld(value, 10);
  }
});
bench.run().then((data) => {
  console.table(data.map((e) => ({ name: e.name, mean: e.result.mean, p99: e.result.p99, p999: e.result.p999 })));
});
