How to get the full history of a HIVE account (JS)

This is how I get the full account history of a given HIVE account with dhive

Not included are virtual ops, as that's a different call entirely.
I had solved this before, but this time my solution is kind of neat, so I wanted to share, in case someone else did not find that trivial.

<script src="https://unpkg.com/@hiveio/dhive@latest/dist/dhive.js"></script>
<script>
let account = 'bittrex-richie';
let client = new dhive.Client(["https://api.hive.blog"]);

class AccountData {
    constructor(account, client) {
        this.account = account
        this.client = client             
        this.operations = []
    }
    load(start = -1, limit = 1000) {
        return new Promise(resolve => {                            
            this.client.database.getAccountHistory(
                account = this.account, 
                start = start, 
                limit = limit
        )
            .then((operations) => {                    
                for (var operation of operations.reverse()) {   
                    this.operations.push(operation)
                } 
                if (start == -1) {
                    start = operation[0] - 1
                } 
                else {
                    start = start - limit
                }
                if (start <= 0){                        
                    resolve()
                    return
                }
                if (limit >= start) {
                    limit = start
                }
                this.load(start, limit).then(resolve)                    
            })
        })
    }
}   
var ada = new AccountData(account, client);
ada.load().then(() => {        
    for (operation of ada.operations) {
        console.log(operation)
    }
})
