### Building and Sending CKB Transactions in REPL

Source: https://github.com/ckb-devrel/offckb/blob/master/README.md

This JavaScript snippet demonstrates how to construct, complete, and send a CKB transaction within the OffCKB REPL. It utilizes `ccc` for fixed-point calculations and transaction creation, `SignerCkbPrivateKey` for signing, and `completeInputsByCapacity` and `completeFeeBy` methods to finalize the transaction before sending.

```JavaScript
OffCKB > let amountInCKB = ccc.fixedPointFrom(63);
OffCKB > let tx = ccc.Transaction.from({
...   outputs: [
...     {
...       capacity: ccc.fixedPointFrom(amountInCKB),
...       lock: accounts[0].lockScript,
...     },
...   ],
... });
OffCKB > let signer = new ccc.SignerCkbPrivateKey(client, accounts[0].privkey);
OffCKB > await tx.completeInputsByCapacity(signer);
2
OffCKB > await tx.completeFeeBy(signer, 1000);
[ 0, true ]
OffCKB > await mySigner.sendTransaction(tx)
