What this snippet does
Async functions automatically wrap their return type in a Promise, but Awaited can unwrap it back to the inner type.

Why practise typing this
Typing async & promises code builds muscle memory for the symbols and indentation TypeScript uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
