This is part of the spec. That statement is false unless I'm missing something major here. Promises aren't resolved in the next turn of the event loop. They should be resolved as part of the microtask queue which can happen at the end of the tick (recursively). Example (tested on node 8): Promise.resolve() .then(() => console.log('1')) .then(() => console.log('2')) .then(() => console.log('still the same tick!')); setTimeout(() => console.log('timeout happening in the next tick'), 0); Result: 1 2 still the same tick! timeout happening in the next tick The same will happen with async functions: (async () => { console.log(await Promise.resolve('1')); console.log(await Promise.resolve('2')); console.log(await Promise.resolve('still the same tick!')); })(); setTimeout(() => console.log('timeout happening in the next tick'), 0);
