Those are the address bytes. You should be able to get the string address using something like:

```javascript
const rec = algosdk.encodeAddress(confirmation.txn.txn.rcv);
```

or for an asset

```javascript
const rec = algosdk.encodeAddress(confirmation.txn.txn.arcv);
```

I totally missed the issue you were having. The JS SDK has an issue handling larger assetid/appid numbers than 2^53. This will be fixed in the future. It will be a long time before it matters (>10,000 years), so for now you are pretty safe just using number.
