The result of an async function is a Promise, which will be resolved at some later time with the actual return value. Inside another async function, you can await that Promise to get the return value: If an async method doesn't use an Await operator to mark a suspension point, the method executes as a synchronous method does, despite the Async modifier. The compiler issues a warning for such methods. Async and Await are contextual keywords.
