Very nice and concise tutorial.
I noticed you don't use promises, is there a reason for this? Steem-js api comes with bluebird as a dependency. It already provides Async methods. For example, filtering can be done as:
steem.api.getAccountHistoryAsync(ACCOUNT_NAME, -1, 50)
.filter( tx => tx[1].op[0] === WALLET_FILTER )
.each((transfer) => {
displayTransactions(transfer)
})
You may want to checkout my tutorial from awhile ago that shows account history traversal by date using generator functions and promises.

hey, I did not realise Steem-js had bluebird as a dependency, that's pretty cool. I avoid using promises in the tutorials because I feel promises are less approachable to newer developers. As per your example, it does produce far cleaner code. I'm totally going to look at where I can implement some of this style into my projects and dig through your other tutorials. Thanks!
