From name to uint64

Here is how eosio account name is computed to uint64.

"eosio",
"eosio.msig",
"eosio.token",

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

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

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.

const generate = require('nanoid/generate');
const alphabet = '.12345abcdefghijklmnopqrstuvwxyz';
generate(alphabet, 12); //=> "nc4zs1yyg.jx"
