How to use the bs58check.encode function in bs58check

function getAddress (d, compressed) {
  var Q = curve.G.multiply(d).getEncoded(compressed)
  var hash = hash160(Q)
  var payload = Buffer.allocUnsafe(21)
  payload.writeUInt8(0x00, 0) // XXX TODO FIXME bitcoin only??? damn you BIP38
  hash.copy(payload, 1)

  return bs58check.encode(payload)
}

function getAddress(publicKey, version){
	var pubKeyRegex = /^[0-9A-Fa-f]{66}$/;
	if(!version){
		version = networkVersion;
	}
	if (!pubKeyRegex.test(publicKey))
		throw "publicKey is invalid";
	var buffer = crypto_utils.ripemd160(new Buffer(publicKey, "hex"));
	var payload = new Buffer(21);
	payload.writeUInt8(version, 0);
	buffer.copy(payload, 1);

	return bs58check.encode(payload);
}

get: function () {
    return bs58check.encode(serialize(this, this.versions.public, this.publicKey))
  }
})
