node test.js

/home/users/test.js:4
console.log(res.version.toString('hex')) // => 80
^
TypeError: Cannot call method 'toString' of undefined

while the script is just like in the example:

var cs = require('coinstring');

var wif = "5Hx15HFGyep2CfPxsJKe2fXJsCVn5DEiyoeGGF6JZjGbTRnqfiD"
var version = 0x80 //Bitcoin private key

var fromBtcWif = cs.createDecoder(version)

//later in your program
console.log(fromBtcWif(wif).payload.toString('hex'))
// => 51184cd2cdd640ca42cfc3a091c51d549b2f016d454b2774019c2b2d2e08529fd

I'm not sure that I understand what problem you're describing... what is res in your code?
