You can await in a normal function in better languages, just not in JavaScript. | ||||||||

Await, per common definition, makes you wait asynchronously for a Task/Promise. How on earth are you going to "await" for a Promise which also runs on the same thread on a synchronous function? That function needs to be psuedo-async as in "return myPromise.then(() => { /* all fn code here */ }), or you need to use threads, which brings us to the second point... With the closest thing to threads (workers) in JavaScript and using SharedArrayBuffer and a simple while loop, perhaps (didn't think too much on it), you can implement the same thing with a user defined Promise alternative but then why would you want to block the main thread which usually has GUI/Web-Server code? | ||||||||
