Write Async Functions with the async/await Operators

async / await should really be thought as a better way to use Promises reliably and safely with less chances of programming errors.
This lesson covers the fundamentals of annotating a function as async. An async function gets the chance to use the await keyword. This lesson covers the usages of these keywords.

That would work. However angular will not wait for for the promise chain to complete.
Good to know
