@marcincharezinski agreed, maybe we can remove the async modifier as well. @joeheyming what do you think?

[jonhermansen]

@qiyigg I just pushed a commit to make getGreetingText synchronous as well. Makes sense to me. The async/await version of the code prefixes the function call with await, and Jasmine's expect() is able to resolve the promise anyway in the non async/await version. I agree that the function doesn't need to be async now +1

[joeheyming]

works for me
