Node: Await without catching ? It's really bad...

index.js

const Test = (ms) => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      if(ms === 20) reject(new Error('Bad value'));
      resolve('ok');
    }, ms);
  });
}

async function testUnhandled()  {
  const res1 = await Test(10);
  const res2 = await Test(20);
  console.log('Test done.');
}

async function testHandledByTryCatch()  {
  try{
    const res1 = await Test(10);
    const res2 = await Test(20);
    console.log('Test done.');
  } catch (e) {
    console.log('Error handled (global): ', e);
  }
}

async function testHandledByCatch()  {
    const res1 = await Test(10).catch((e) => console.log('Error handled (res1): ', e));
    const res2 = await Test(20).catch((e) => console.log('Error handled (res2): ', e));
    console.log('Test done.');
}

testUnhandled();
testHandledByTryCatch();
testHandledByCatch();

Output:
