Can you await a non async function?
You can use the await keyword on its own (outside of an async function) within a JavaScript module. This means modules, with child modules that use await , wait for the child module to execute before they themselves run.
How are callbacks asynchronous?
Async callbacks are functions that are specified as arguments when calling a function which will start executing code in the background. When the background code finishes running, it calls the callback function to let you know the work is done, or to let you know that something of interest has happened.
What is asynchronous behavior?

When to use return await in an async function?
Since the return value of an async function is always wrapped in Promise.resolve, return await doesn’t actually do anything except add extra time before the overarching Promise resolves or rejects. The only valid exception is if return await is used in a try/catch statement to catch errors from another Promise-based function.

What does the async keyword before a function do?
The async keyword before a function has two effects: Makes it always return a promise. Allows await to be used in it. The await keyword before a promise makes JavaScript wait until that promise settles, and then: If it’s an error, the exception is generated — same as if throw error were called at that very place. Otherwise, it returns the result.
How does an asynchronous function work in node?
It might be hard to understand in the beginning, but once you know, it’s the best thing. It’s also the reason Node is so fast. So, when you have to run an asynchronous function, you also send an extra function to the asynchronous function called a callback function which will be executed once the async operation is done.
