How do I return the response from an asynchronous call?

How do I return the response/result from a function foo that makes an asynchronous request? I am trying to return the value from the callback, as well as assigning the result to a local variable inside the function and returning that one, but none of those ways actually return the response — they all return undefined or whatever the initial value of the variable result is.

he A in Ajax stands for asynchronous. That means sending the request (or rather receiving the response) is taken out of the normal execution flow. In your example, $.ajax returns immediately and the next statement, return result;, is executed before the function you passed as success callback was even called.

The ECMAScript version released in 2017 introduced syntax-level support for asynchronous functions. With the help of async and await, you can write asynchronous in a "synchronous style". The code is still asynchronous, but it's easier to read/understand.

How does the "DisplayManager" populates various fields?

How does Android set various fields of the "DisplayManager" fields? For example, "name" ? Also, it has a field called "deviceProductInfo" which has various details of the connected display. How Android populates all these fields during run time?
