Async and Await
await are special syntax for working with promises.
A function marked as
async always returns a
Promise — if we return a non-promise value, it's automatically wrapped in
Within the function, we can use
await to wait for a promise to be resolved or rejected and access its value.
The main advantage of this syntax is that we don't introduce deeply nested callback chains. However, all the complexity of asynchronous programming is still here, even if the syntax looks nicer.
