I have this function on a class. It is returning a promise. static blabla(): Promise <number> { return new Promise < number > ((resolve) => { resolve(999); }); } This function works fine but I would like to confirm if…
I know that generators paired with iterators can be used to write async code, but what’s the benefit of using it? I’ve heard it offers more fine grained control than promises, but so far I haven’t seen a case of…
If I call an async function that doesn’t explicitly return anything from the await, will it return a resolved Promise? Or Void? Something else? For example an IIFE like this, or this but it being called in the global scope…

I've tried multiple versions of example code but can never seem to get something that guarantees completion of the query set before other code commences. I was under the impression that 'await' makes the query complete before continuing. I'm running…
I cannot for the life of me wrap my head around what I am doing wrong with this Async/Await concept. Here is my Node.js code below (two separate files). So, the console.log("hasInvoiceAlreadyBeenPaid:", hasInvoiceAlreadyBeenPaid); line runs before the controller.checkIfAuthNetChargedInvoice() has been…
