```
npm i --save bip44-constants
```
```js
const constants = require('bip44-constants')
console.log(constants)
// iterate through constants
// format: constant, coinSymbol, coinName
// ie. [ 0x80000002, "LTC", "Litecoin" ]
// Some rows have no coin and are just indices and constants
constants.forEach(row => {
const constant = row[0]
const coinSymbol = row[1]
const coinName = row[2]
// ...
console.log(coinName, coinSymbol, constant)
})
// Find your coin by using filter
const liteCoin = constants.filter(item => item[1] === 'LTC')
// ---- OR filter on multiple elements if you are aware of duplicates
const liquidBitcoin = constants.filter(item => item[1] === 'LBTC' && item[2] === 'Liquid BTC')
// Be sure to assert there was only one result
assert(liteCoin.length === 1)
assert(liquidBitcoin.length === 1)
console.log(liteCoin[0])
// [ 2147483650, 'LTC', 'Litecoin' ]
console.log(liquidBitcoin[0])
// [ 2147485424, 'LBTC', 'Liquid BTC' ]
console.log(liteCoin[0][0])
// 2147483650 (which is 0x80000002 in hex)
console.log(liquidBitcoin[0][0])
// 2147485424 (which is 0x800006f0 in hex)
