    decimalPlaces: 2,
    keepTrailingZeroes: false,
    render: (literal, symbol) => `${literal} ${symbol}B`,
})

format(4096) // '4 KB'

defaults(4096) // '4.1 kB'

Duration formatter

import { durationFormatter } from 'human-readable'

const span = Date.now() - Date.parse('2019-01-01T09:00:00.000+0200')

const format = durationFormatter({
    // 'y' | 'mo' | 'w' | 'd' | 'h' | 'm' | 's' | 'ms'
    allowMultiples: ['y', 'mo', 'd'],
    keepNonLeadingZeroes: false, // E.g. '1y 0mo 0d'
