Behavior of empty promises in Node.js

Dear Node.js I did not expect this:

• if we do await [number] output is as expected:

(async function main() {
  console.log('STARTED')
  await 123;
  console.log('AWAIT DONE')
  console.log('DOING SOMETHING ELSE')
})()
STARTED
AWAIT DONE
DOING SOMETHING ELSE

• if we do await [null] output is as expected:

(async function main() {
  console.log('STARTED')
  await null;
  console.log('AWAIT DONE')
  console.log('DOING SOMETHING ELSE')
})()
STARTED
AWAIT DONE
DOING SOMETHING ELSE

• if we do await [undefined] output is as expected:

(async function main() {
  console.log('STARTED')
  await undefined;
  console.log('AWAIT DONE')
  console.log('DOING SOMETHING ELSE')
})()
STARTED
AWAIT DONE
DOING SOMETHING ELSE

• but if we do await for some promise which is never resolved, Node.js just silently exits with exit code `0` (success) just after await!

(async function main() {
  console.log('STARTED')
  await new Promise(resolve => {});
  console.log('AWAIT DONE')
  console.log('DOING SOMETHING ELSE')
})()
STARTED
exited with code 0

lines after “await” are never executed.

Node.js just silently exited with exit code `0` (success) just after await!

This is weiiiiiiirrrrrd!
