About

A Hash Mapped Trie implementation for JavaScript.

import crypto from 'crypto-promise'

// decide how to hash buffers made from keys, can return a Promise
const hashFn = async (buf) => {
  return crypto
    .createHash('sha256')
    .update(buf)
    .digest()
}

const bucket = createHAMT({
  hashFn: hashFn
})

await bucket.put('key', 'value')

const output = await bucket.get('key')
// output === 'value'
