How to transfer EOS token using Scatter.js or eos.js?

Question

I've successfully managed to use eosjs to transfer some EOS but when I'm trying to send something else (a token) it's no longer working.

For example that code is working:

import ScatterJS from 'scatterjs-core';

const scatter = ScatterJS.scatter;
const eos = scatter.eos(network, Eos, eosOptions);
const transactionOptions = { authorization:[`${account.name}@${account.authority}`] };
var res = await eos.transfer(account.name,'testacc','1.0000 EOS','', transactionOptions);

Whereas that code isn't working:

var res = await eos.transfer(account.name, 'testacc', '80.0000 EOSDAC', '', transactionOptions);

When executing that second code I get the error (caught in a try / catch handler):

{"code":500,"message":"Internal Service Error","error":{"code":3050003,"name":"eosio_assert_message_exception","what":"eosio_assert_message assertion failure","details":[{"message":"assertion failure with message: unable to find key","file":"wasm_interface.cpp","line_number":917,"method":"eosio_assert"},{"message":"pending console output: ","file":"apply_context.cpp","line_number":72,"method":"exec_one"}]}}

I honestly don't know what's wrong with my code... can anyone help me to get it to work?

After searching the official doc and trying different approches I finally got it to work. I've used eos.transaction instead of eos.transfer and the following example is working for those interested:

var res = await eos.transaction({
    actions: [
    {
        account: "eosjackscoin", //has to be the smart contract name of the token you want to transfer - eosio for EOS or eosjackscoin for JKR for example
        name: "transfer",
        authorization: [{
            actor: account.name,
            permission: account.authority
        }
        ],
        data: {
            from: account.name,
            to: "destinationaccount",
            quantity: "50.0000 JKR",
            memo: ""
        }
    }]
});
