In JavaScript, I am trying to make multiple key updates to etcd in 1 transaction. I've filtered the key-value pairs that I want to update before the transaction so basically I don't have any comparisons to do. I want to use it like this:

const client = new Etcd3({ hosts: connectionString });

...

await client.if(true)
                .then(
                    client.put(entry1).value(JSON.stringify(account1, null, 4));
                    client.put(entry2).value(JSON.stringify(account2, null, 4));
                    client.put(entry3).value(JSON.stringify(account3, null, 4));
                    client.put(entry4).value(JSON.stringify(account4, null, 4));
                )
                .else();

is there anything I can put instead of this true that will act the same way?
