2013年1月22日 · From my understanding one of the main things that async and await do is to make code easy to write and read - but is using them equal to spawning background threads to perform long duration logic? ...

2016年1月16日 · await ActionAsync().Unwrap(); is definitely easier to read between the two. That's about where the differences end.

AFAIK you don't gain anything by adding a second await and async inside Task.Run. And since you aren't passing parameters, that simplifies slightly more to await Task.Run( this.contentLoader.LoadContentAsync );.

2018年4月26日 · await makes no difference to how the fetch API works. You make it a post request in the same way as you would with any other use of fetch.

When using a simple callback such as in the example below: test () { api.on ( 'someEvent', function ( response ) { return response; }); } How can the function be changed to use async / await?

The most important thing to know about async and await is that await doesn't wait for the associated call to complete. What await does is it returns the result of the operation immediately and synchronously if the operation has already completed or, if it hasn't, it schedules a continuation to execute the remainder of the async method and then returns control to the …

2013年3月20日 · I've stumbled into this problem a few times and I'm sure it's a common problem which must have a common solution. How do I safely call an async method without awaiting the result? Update: For people suggesting that I just await the result, this is code that is responding to a web request on our web service (ASP.NET Web API).

List<T>.ForEach doesn't play particularly well with async (neither does LINQ-to-objects, for the same reasons). In this case, I recommend projecting each element into an asynchronous operation, and you can then (asynchronously) wait for them all to complete. using (DataContext db = new DataLayer.DataContext()) { var tasks = db.Groups.ToList().Select(i => …

2018年6月8日 · I've read many examples, blog posts, questions/answers about asyncio / async / await in Python 3.5+, many were complex, the simplest I found was probably this one. Still it uses ensure_future, and ...

As far as I understand, in ES7/ES2016 putting multiple await's in code will work similar to chaining .then() with promises, meaning that they will execute one after the other rather than in paralle...
