Functions
pipe()
Until the pipe operator becomes part of JavaScript you can use this utility to create pipelines.
const add = (a, b) => a + b;
const add10 = x => add(x, 10);
const add100 = x => add(x, 100);
const sum = pipe(1, add10, add100);
sum === 111; // true
A pipeline is one solution to performing consecutive operations on a value using functions, such as you would when building a transaction.
const transferTransaction = pipe(
// The result of the first expression...
createTransaction({ version: 0 }),
// ...gets passed as the sole argument to the next function in the pipeline.
tx => setTransactionFeePayer(myAddress, tx),
// The return value of that function gets passed to the next...
tx => setTransactionLifetimeUsingBlockhash(latestBlockhash, tx),
// ...and so on.
tx => appendTransactionInstruction(createTransferInstruction(myAddress, toAddress, amountInLamports), tx)
);
