this should work:

async () => {
  try {
    const result1 = await firstAsynchronousFunction();
    const result2 = await secondAsynchronousFunction(result1);
    console.log(result2);
  } catch(err) {
    throw new Error(`Something failed`);
  } finally {
    console.log(`All Tasks are Done`);
  }
}

Actually my main question was using Promise.prototype.catch() in async/await ES8 syntax, Undoubtedly Promise.prototype.then() is existed in essence of async/await syntax.

I searched about using Promise.prototype.catch() in async/await and found this:

async () => {
  try {
    const result1 = await firstAsynchronousFunction();
    const result2 = await secondAsynchronousFunction(result1);
    console.log(result2);
  } catch(err) {
    throw new Error(`Something failed`);
  }
}

And absolutely I knew about Promise chaining, like:

new Promise((resolve) => {
  console.log(`Initial`);
  resolve();
})
.then(() => {
  console.log(`Task Number One`);
})
.catch(() => {
  console.log(`Task in Error`);
})
.finally(() => {
  console.log(`All Tasks is Done`);
})

So, my question is how I can use finally in async/await syntax?
