## From name to uint64

Here is [how eosio account name is computed to uint64](https://github.com/EOSIO/eos/blob/master/libraries/chain/include/eosio/chain/name.hpp#L21).

```text

"eosio",

"eosio.msig",

"eosio.token",

---- 6138663577826885632

---- 6138663587900751872

---- 6138663591592764928

```

## From uint64 to name

Source https://github.com/EOSIO/eos/blob/master/libraries/chain/name.cpp#L19

## Example

Try on run-kit https://npm.runkit.com/eosjs-account-name

```javascript

const eosjsAccountName = require('eosjs-account-name');

const n = eosjsAccountName.nameToUint64('eosio');

console.log('eosio to uint64: ' + n);

console.log('uint64 to name: ' + eosjsAccountName.uint64ToName(n));

```

### Parse symbol name

[symbol.test.js](./__tests__/symbol.test.js)

```javascript

const { symbol, nameToUint64 } = require('eosjs-account-name');

/**

 * cleos -u https://eos.greymass.com get scope eosio.token -t stat

 */

const name = '........ehbo5';

const uint64 = nameToUint64(name);

const symbolName = symbol.toName(uint64);

// expect(symbolName).toEqual('EOS');

```

## Note on random eosio name

In case you want to generate a random name, I suggest you use [`nanoid`](https://zelark.github.io/nano-id-cc/).

```javascript

const generate = require('nanoid/generate');

const alphabet = '.12345abcdefghijklmnopqrstuvwxyz';

generate(alphabet, 12); //=> "nc4zs1yyg.jx"

```
