I have this code:

setTimeout(function timeout() { console.log('timeout'); }, 0); let p = new Promise(function(resolve, reject) { console.log('create promise'); resolve(); }); p.then(function(){ console.log('execute promise'); }); console.log('end');

I get this order when execute the code:

• create promise
• end
• execute promise
• timeout

Question: Why create promise is executed first? I expect to execute first end, because it is the only one synchrone code so it should be first executed.
