Power up using steemjs

Hi friends,

Here is an small code to power up using steemjs. Its working and I will share the small code block.

var steem = require('steem');
steem.api.setOptions({ url: 'https://api.steemit.com/' });
steem.broadcast.transferToVesting('WIFHERE','user1','user2','1.000 STEEM', function(err, result) {console.log(err, result);});

---

It works but I have few issues at the moment.

1. I do not know why it seems kind of stock in the nodejs console.
2. Code returns null and and object
   
3. It hangs after that.

Does anyone knows how to convert SBD to STEEM using #steemjs?
Any ideas?
