Summary of knowledge points

1. await Must be in async Use in decorated functions , In order to execute the code sequentially , Don't use await Words , The code is asynchronous , And not in sequence , Because if the lower code needs the result returned by the upper request, it can be executed downward , You can use it await, Although used await 了 , But the code is not synchronized .
2. About await The decorated code is not synchronized , But it is executed in sequence , Because await After the modified code is compiled, it is still called asynchronous code （ Why do you say that , Because of await This grammar can only be used in async It's used inside ）, Actually await It is equivalent to grammar sugar , The effect of synchronous code is achieved by calling asynchronous tape .
