For example:

const BitShares = require("btsdex");

async function start() {
  BitShares.init("wss://bitshares.openledger.info/ws");
  await BitShares.connect();

  let bot = new BitShares("jjb777", "yourPrivateActiveKey")

  await bot.transfer("scientistnik","BTS", 10)
  console.log("Transfer sent")
}

start()
