Paying lumens from root account to a keypair.

Should this operation be wrapped in a transaction? Also, I know, that the source is optional. However, the explanation on the page is not clear; "Defaults to the transaction's source account.". For now, I am using the root account because, I want to fund this account to begin with.

This is my approach:

var transaction = new StellarSdk.TransactionBuilder(sourceAccount)
  .addOperation(StellarSdk.Operation.createAccount({
  destination: destinationId,
  startingBalance: xferAmount,
  source : sourceKeys.publicKey()
}))
  .addMemo(StellarSdk.Memo.text('Test Transaction'))
  .build();
  
transaction.sign(sourceKeys);
server.submitTransaction(transaction);

ok, this is what I get:

/home/champ/node_modules/stellar-base/lib/transaction_builder.js:143
                var sequenceNumber = new BigNumber(this.source.sequenceNumber()).add(1);
                                                               ^

TypeError: this.source.sequenceNumber is not a function

This is what I am using:

StellarSdk.Network.use(new StellarSdk.Network(NETWORK_PASSPHRASE));
var opts = new StellarSdk.Config.setAllowHttp(true);
var server = new StellarSdk.Server(HORIZON_ENDPOINT, opts);
var sourceKeys = StellarSdk.Keypair.fromSecret(fromWallet);
var destinationId = toWallet;

var transaction = new StellarSdk.TransactionBuilder(sourceKeys.publicKey())
  .addOperation(StellarSdk.Operation.createAccount({
    destination: destinationId,
    startingBalance: xferAmount,
    source : sourceKeys.publicKey()
  }))
  .addMemo(StellarSdk.Memo.text('Test Transaction'))
  .build();
  
transaction.sign(sourceKeys);
server.submitTransaction(transaction);

Yay! Got it working now. Thanks, dzham ?

Here is my final attempt.

var sourceKeys = StellarSdk.Keypair.fromSecret(fromWallet);
var destinationId = toWallet;

server.loadAccount(sourceKeys.publicKey())
  .then(function(sourceAccount) {
    var txn = new StellarSdk.TransactionBuilder(sourceAccount)
                .addOperation(StellarSdk.Operation.createAccount({
                    destination: destinationId,
                    startingBalance: xferAmount
                  }
                  )
                )
                .addMemo(StellarSdk.Memo.text('Test Transaction')
                )
                .build();
                
    txn.sign(sourceKeys);
    return server.submitTransaction(txn);
    })
  .then(function(result) {
    console.log('Success! Results:', result);
  })
  .catch(function(error) {
    console.error('Something went wrong!', error);
  });
