Javascript Code To Do Radix sort

const arr = [3,2,1,4,6,5,7,9,8,10]

const getDigit = (num, i) => Math.floor(Math.abs(num) / Math.pow(10, i)) % 10

const digitCount = num => {
    if (num === 0) return 1
    return Math.floor(Math.log10(Math.abs(num))) + 1
}

const mostDigits = nums => {
    let maxDigits = 0

    for (let i = 0; i < nums.length; i++) maxDigits = Math.max(maxDigits, digitCount(nums[i]))

    return maxDigits
}

const radixSort = nums => {
    let maxDigitCount = mostDigits(nums)

    for (let k = 0; k < maxDigitCount; k++) {
        let digitBuckets = Array.from({ length: 10 }, () => [])
        
        for (let i = 0; i < nums.length; i++) {
            let digit = getDigit(nums[i], k)
            digitBuckets[digit].push(nums[i])
        }

        nums = [].concat(...digitBuckets)
    }

    return nums
}

console.log(radixSort(arr)) // [1,2,3,4,5,6,7,8,9,10]
